I think it makes a lot more sense to clean room it. Most (all?) of the functionality is already present in the Windows kernel, there just needs to be a Linux compatible API exposed.

The alternative is to... run two kernels? I doubt that's feasible in any form that doesn't resemble running a Linux VM.

The NT kernel has had a POSIX subsystem since the beginning. I'm not sure whether WSL uses this though.
