First, I state that I do not know L4, so I can't judge it.
(And don't have the time for it.)

But how easy/difficult will it be to rewrite/extend to our purposes?

How about CPU specific features given in VAX/AXP architecture reference
manual, how is it possible to implement those?
(For my 0.3, I had modified the kernel's interrupt entry point a bit.) For
instance, how will AST, IPL etc be handled with L4?

How to fit in the QIO and VMS device driver system with L4?

And the other hardware/system-specific issues?
