Is there a way I can view 2 different bin files of the same type (ie comments.bin) and find the differences, and then edit the current .bin with values from the old, if needed?
or
Can I get the format of the various bin files so I can create my own program to scan and combine
Maybe this could be a suggestion for new feature?

Sorry, Advanced IP Scanner do not have such function.
We added this to our wishlist for the developers.
