I really hope that this is for nothing more serious than an ACME::* module since I would hate for anyone to rely on code that tries to do something like this. It sounds extremely fragile.

How are you going to recognize pointers to the thing that you're adjusting? Are you just going to do a substitution and pray that anything whose bytes are the address of that location really is a pointer to that location? Sure it is only 1 in 4 billion odds of being wrong, for each place you start a set of 4 bytes. Which means that if you did this on a process that was at 40 MB, you'd have 1% odds of randomly going wrong. And when you did go wrong, good luck debugging it!
