It seems like the latter would be a lot less effort and result in a system that was easier to track the original sources going forward.

As I heard, the largest work in porting Pla= n 9 to L4 enviroment
is rewriting Plan 9's C code base =A0to be compiled on gcc
as L4 uses the compiler for its development.

The developers of LP49 themselves could chime in, but here is the link
to the project.
You might be surprised how much of Plan 9 has been rewritten in LP49.
