Can I update the Adapter EF-EOS R 0.71x with a R5 C?

Can I update the Canon Mount Adapter EF-EOS R 0.71x with an R5 C camera or do I need a C70 for the update? I don't have a Canon Mount Adapter EF-EOS R 0.71x yet but I want to purchase one for my R5 C. I wanted to know if I can update the firmware before I purchase the adapter. The image attached was taken from a youtube video demonstrating updating the adapter's firmware with a C70.

OK, you've clearly thought this through, and you certainly have a more specialised use case than normal.  Just bear in mind that an 8k resolution is NOT 8k pixels; it's 8k photosites.  With oversampling, you can get something like a true 4k pixel resolution out of the camera.  But with the APS-C crop, I don't know how that works -- I don't know what the downscaling would look like, as the camera has several different modes.

I actually tested the R5C for resolution in a bunch of different scenarios: https://moonblink.info/MudLake/gear#R5C  @ 16:22

Resolutions don't matter, the worlds most advance digital video/cinema camera the ARRI ALEXA 35 shoots in 4.6k.
