The problem with the standard flash units is that you might get shadowing from the lens given the relatively short working distance. I think the macro flash gives you a lot more flexibility.

Small diffusers are generally pretty useless because they just tend to reduce the light output, I always use a 7" x 5" diffuser on a single flash with a 100mm lens. With most macro subjects you still need a certain amount of directional lighting otherwise the shots appear too flat and dull.
The MPE lens can cause all sorts of problems with lighting because you are working so close to the subject and putting a flash and diffuser into the equation can be quite tricky. I doubt that you will find one flash setup that will work well with both lenses.

Where did the 60mm come from? In the OP you were talking about the 100mm and the MPE 65!
If this is bench to studio macrowork, you might try a light tent to provide diffuse light all around the subject

Do you know which diffusion material(s) can be used in addition to using a 7 x 5 soft box? And I have another question. Is it preferable to use E-TTL or manual mode for macro photography including focus stacking?
Parachute silk works very well, or the modern synthetic equivalent which is widely available on that well known auction site. It gives good diffusion without blocking too much light and can be used multi layered if necessary. Some people have tried everything from plastic milk bottles to expanded polystyrene, most materials have their good and bad points.
When I use flash for macro then I always use ETTL with the camera in manual mode, that way you have control of both shutter and aperture while the camera controls the flash output.
Better shots can be made in natural light but it is pretty rare to get bright soft natural lighting in the same place as your macro subject especially if you are photographing insects.

However, I had an idea of using a rechargeable clip-on LED book light with a flexible gooseneck as a source of light because it can be set in any direction and position as desired, and has dimmable settings depending on lighting conditions. With creativity, I can perhaps diffuse it with silk parachute cloth to soften the light.
Not sure that a single LED light will be much use as it is a smaller point source of light than a flashgun and a lot less light. The secret of diffusion is to spread the light and create a larger light source so just putting a small diffuser on a single LED will achieve very little diffusion and absorb a lot of the light.
Unless you get the right LED then you will have colour temperature problems and although these can easily be corrected when shooting raw it can be a problem if you are mixing the LED lighting with daylight.
