Merge Modules?

I would like to add a few maps and counters from the SPQR Vassal 2.5 Module to the Command & Colors Ancients Module 4.1 - is this possible?

If so how would I do it?

So I have a SPQR Heraclea map jpg and I just want to load it into the CC map options. I put it in under Main Map/Map Boards and copied all the Multi Zone grids (with the same coordinate numbers) for the game cards yet it fails to load. Is it because I am missing something on how to size the individual grid coordinates?
