I'm running Bob's and RFP together. There are a couple things - hydrogen and deuterium - that aren't treated as equivalent across the two. Is there a simple method that I can employ so that Bob's recipes will accept RFP hydrogen/deuterium and vice-versa?

not that I'm aware of, I'm not familier with RFP, what's the full name of the mod?

but it would probably require somebody to write a conversion recipe, or a script to replace one of the fluids with the other.

I've heard mention of some compatibility issues between my mod and that one. But I'm not really in the loop anymore, and haven't looked at modding for a few months.

I'll see if I can work out a compatibility module that'd enable itself if RFP is detected, and if it works out, I'll toss it your way. :)
