Well... Magisk, Riru and LSPosed are now working on WSA!
Brief steps (note this is just a tmp solution)
1. Enable dev mode in win, extract WSA package, disable its signature verification, remove private permissions, and sideload it.
2. Download kernel sources of WSA, write a kernel module to provide su, compile it and relpace the kernel.
3. With su, compile magisk and run its emulator.sh script, then grant su to adb.
4. Compile Riru commenting out codes that restart zygote and install it.
5. Download and install LSPosed.
6. adb reboot userspace.
7. Enjoy :)
