Amen, brethren! :-)
Interestingly, it looks like there is exactly ONE call to fork() in the bash
source.
But -- it's in a function that gets called all over the place, with large
amounts of
setup and post-fork processing, on both sides (parent/child). It might be
possible to
substitute spawn in some cases but, as you noted, it wouldn't be easy.

One for the "too hard basket" then Jerry?! It would be fantastic to have
bash as the default shell for z/OS but that
ain't gonna happen anytime soon :)
