Using Armada for fleet battles when it first comes out probably won't work too well IMO. It would only work if you limit yourself to the capital ship classes that have appeared in Armada. That means no ISDs or MC80s until they come out and some of the ship models scheduled to appear in Armada haven't appeared in the RPG yet.
Plus there's the C90 issue. Namely Armada has stats for 2 models of CR90, the CR90A and CR90B, but AFAIK nothing has specified which, if either, of these CR90 variants is the one that appears in the RPG.
