Well, if you ask the Asahi Linux team, heck no this isn't possible. Windows doesn't understand the Apple Interrupt Controller and a driver (at least in theory) should not be able to fix that without major kernel changes.
However, they actually address this with the "What makes Windows on M1 hard?" area and talk about using a vGIC to do an extremely lightweight pseudo-hypervisor as a workaround. An interesting theory.
The main issue though is that Windows for ARM isn't for sale and can't be legally purchased outside of buying a WoA device. Microsoft could send a legal letter at any time.
"If the author doesn't distribute any Microsoft IP, there's nothing Microsoft can do."
Only in theory. Microsoft could allege DMCA violations, or any number of threats. They might not have merit but they are still scary and could shut down the project regardless.
