Funny story. LG made something with a similar concept about 10 years ago and it never really took off. The LG G5 was a modular smart phone that was supposed to have a bunch of cool modules, but they never came to fruition.
I had one, but mostly because I loved having a swappable battery. Never had to charge my phone, I would just have a spare battery charging on my desk and I would swap it out before I left the house.
While this article is about upgrading to Win11, not necessarily a clean install, I found the best way to bypass the requirements is to make an autounnatend with Schneegans.de . Make a Win11 installation USB, generate an autounnatend to bypass the requirements, remove bloat, allow offline install (local account instead of Microsoft account), and a couple other little tweaks like dark mode etc. Drop the xml on the root of the flash drive, and boom.
Or… You know… Install Linux.
