They should just suck it up already and add some ships from the prequels/clone wars. It's already been established that at least a few of them still were in use during the rebellion era by at least one of the three factions if not multiple.
Yea a few ships wouldn't work because they mostly died off during the clone wars (delta 7, possibly N-1, etc). But most would work.
Instead of adding more EU ships that will get more and more obscure they should add prequel MOVIE ships all of next year. Then the following year they can do ep7 ships if they want.
