I'd think the easiest, as a first step would be to mimic the extended
C they provide and then, maybe, provide for dynamic thread allocation
from within the kernel (see below).

Yes, it is possible. However I think tasking support requires a kernel
such as the OpenRavenscar kernel[1].

nice hobby project will be very valuable anyway.
