I imagine it would be a big lift. Asahi linux is managing through reverse engineering the hardware support, without any official documentation. Even with official documentation it would be a significant change from other aarch64 hardware.
Arm-based windows support via Parallels does work, but AFAICT there's no official way to buy a Windows license due to a Microsoft/Qualcomm partnership.
I think WoA used to be exclusive to Qualcomm, but that hasn’t been true for at least a couple years, maybe longer.
