Possible, certainly. Simple? That's a different question :-)

In general I would favour trying to clean up QEMU's code so
that it is less interdependent (which would make it I think
easier to maintain and test, as well as potentially easier
to use in other contexts); but I think we need to try to tackle
that gradually and doing the easier bits of disentangling first.
