I have never purposely tried it. But, you can probably pull it off using a high frame rate, provided your subjects are neither moving quickly or close to the camera.
For example,I have captured pano shots of a bridge with moving vehicles, The individual frames are fine, and are free of any motion blur from moving vehicles. The only potential for real issues would occur at where the images overlap. The stitching algorithms tend to throw away differences, and keep what is similar.
Provded your subjects are not moving any significant difference across the frame from one shot to the next, you should be fine under those circumstances.

Thank you for your responses. I guess I should tell a little of the backstory.
For several years I have been a bird photographer, using the 7DII and a Canon 100-400 mm II lens. While hiking, we met another hiker who was doing panoramic photography, and I became interested. Something else to learn. So I set about photographing a unique Monterey Cypress tree at Point Lobos, near Carmel, Ca. I wanted to make a panorama that included a little of its surroundings, on a cliff above the ocean. It was an experimental adventure, camera handheld in portrait orientation, using a couple of ideas I had gleaned from online reading. Namely, shoot at high f-numbers for DOF (not really so relevant in this case since the subject was not so close) and in manual mode with fixed focal length. It turns that a panorama does not enhance the Cypress tree. See the Monterey Cypress below. It has a name: the Old Veteran.
I also took single shots of the Cypress at f/8 that looked a little better than the ones that were to be part of the panorama, taken at higher f-numbers, which got me thinking about diffraction. Thus the derivation that shows the diffraction depends on lens f-number in a straightforward way.
Yesterday I received an L-bracket for the 7DII and will use it on my tripod for the next reound of tests with various f-numbers.

You should not need an L-bracket with the 100-400mm, or a 70-200mm. With those lenses you should be using the tripod foot, not an L-bracket, anyway. Rotate the camera to portrait mode within the lens collar.
I shot the bridge using a 70-200mm, and rotating the rig within the tripod ring on the lens. Capturing a panorama does not capture more detail, at least not exactly. I could capture a similar angle of view shooting the bridge at 24mm. But, I can create a higher resolution final image by capturing a series of pano shots while zoomed in on the details. I shot at 7
I shot the bridge with a 20MP 6D. The final image was 38MB. The pixel resolution of the final pano image was, of course, much higher than the 20MP image shot at 24mm.
It seems like you were some distance from this beautiful tree. Capturing a pano image of the tree and its immediate surroundings with a long lens should have more detail than a single photo with a similar angle of view captured using a shorter lens.
But, the individual samples captured for a panoramic shot will not look any better than a single still of the same scene that was shot at the same focal length. The longer lens allows you to zoom in on the details that elude a wider angle lens.
[EDIT] I forgot to add the reason I posted the bridge photo. It was shot in Av mode, at ISO 100. Each frame used an 8 second shutter speed. My shooting position forced me to have a sidewalk between me and the bridge. I could not set up camp in the middle of the sidewalk.
During the course of capturing the shots, a couple of joggers passed in front of the camera, as well as a couple that walked past the camera. Seeing how I was piddling with my smart phone while the shutter was open, they never realized that I was capturing a shot. I reshot the sequence. But, the original shots showed no trace of anyone having crossed in front of the camera, which is no doubt due to the long shutter speed.
Ed,
"How do you do a pano, composed of several shots, with movimg subjects?"
You really can't. Or at least, you need to be aware of some compromise. The bridge photo, which I have seen many timers on here is beautiful, for sure, but you notice there is no definition in the water in the foreground. That is probably due to the fact it was moving waves or ripples.
A person or animal in a single frame will still remain sharp unless it is next to a seam area. If there is too much motion in the various shots Lightroom will not merge them.
I don't necessarily agree with a multi-shot pano being better IQ. It is certainly a bigger file but the individual shots are no more higher IQ than any one single shot. This would greatly depend on camera, lenses and conditions. Panos are different than multi-focus stacking which can increase IQ. Panos take multiple shots and puts them together using LR, or some other software, to allow a wider final photo. Usually because it can exceed what can be contained within just a single frame.
What you may not know is panos also have issues with parallax. A way to correct for parallax error is to use a nodal slide. I don't bother because I am not interested in the highest IQ of these shots because of their final usage. Which is another factor in your decission making, how is the photo going to be used. In fact the two shots shown were hand held using my 1DX, 24-70mm f2.8L lens @ f9.5 (using P mode
), SS 1/350 and ISO 200.
