Yes. Why?
LinuxSBC
He's pretty much the quintessential QA tester. He wants to do things his way, regardless of whether or not the OS wants him to do that. He's usually skilled enough to fix anything he messes up, but he doesn't know enough about Linux to do that, so he ends up breaking things. I feel like most people have a better experience than he did, but his technique uncovered a ton of bugs and usability issues that significantly improved the Linux desktop to have fixed.
Dual-boot, and if anything is missing, boot back into Windows to do that while you work on figuring out how to do it on Linux. There might be something to do what you're asking, but I find it unlikely because Windows and Linux are very different internally.
That should work. One of the benefits of Wayland is that it's better at scaling than X11. What version of KDE are you running? Is there a switch between two different types of scaling (one is blurry for XWayland applications but works for all of them, the other is sharp for all applications but only some XWayland applications and all Wayland applications work)?
In my opinion, phone cameras are usually used to capture a memory, not a moment. Memories are idealistic and inaccurate, so I don't think it's a problem that a way of "storing memories" is also inaccurate.
It would be largely fine, but be careful. Being immutable, a lot of things that you would expect will work differently or not at all. I would not recommend it, but if you're in for a challenge, it's not bad.
