I pretty much found what I need by looking at how the source code for tiffsplit works, then adapting it to write multipage output with altered tags.
... seems like a good opportunity to contribute, and also post the solution to your problem as you've found it. That way, all future archive users and such will enjoy seeing a relevant answer when they're faced with similar issues, and not just a question.
