Quite easy if we stick to the header signature.

I think there are 2 ways :
-write your own Forth ELF relocating code (might be fun, but beside that...)
-have the "init-program" command do this work for you, which require you
to load the image where "boot net" loads it (or maybe other commands,
but for now I only know about boot net as it is the only way to
currently boot grub2 on sparc64 ;) ).

I think this one can't be done without making the FCode grow quite big.

I would be interested if the port could be unified in 32bits. For now I
built it 64bits - don't ask why :) - but if a 32bits build can work both
on sparc32 and sparc64, I think it would be great for maintenance.
