I don't really consider emumain.c a part of the core any more.
With the hooks implemented all over emu.c, it will be just another
module - just like elfemu.c - that uses the core (which is basically
emu.c, plus the fcpu_opcodes library).

Similarly, yes.  I will use pointers to functions, so that other
modules can provide their own versions easily, and change them on
the fly if necessary.  I didn't finish the interface yet, though.
