I believe this question is asked regularly on Internet, but I haven't found a tool that does the above.

Maybe I am overlooking something.
Any suggestions?

I don't recall any pst compare tools, sorry. If i had two that were not the same size and wasn't sure about dupes, i would import one into the other and tell it to skip dupes. You could also use a dupe remover tool that looked across pst files (it would even slower that importing and skipping dupes).
