You mean you've got that many blank hulls and want to know what classes to build them as? Makes absolutely no difference.
Remember, what your list is composed of plays a fairly small roll in BFG - at least, a much smaller roll than in GW's other games. BFG is a game about tactics. Take ship classes that interest you, and learn to use them properly.
General advice, though, is to take a variety of classes and of weapons types. While a list of just batteries or just lances or just ordnance is possible, it's fairly difficult to work with. Being heavy in one weapon type is fine, just make sure to have a little bit of everything. It'll pay off.
Also, you didn't mention anything about Escorts. I don't know if that means you don't have any, or if you were just leaving them out because they're irrelevant to your question. If the former is true, then I suggest you pick up quite a few. Imperial fleets (as with most BFG fleets) *need* Escort support. I go so far as to say that one squadron of 3-4 Escorts per two Cruiser-sized vessels or larger is a good rule of thumb. As above, a good variety works well. Cobras, though, are great little ships - I'd definitely suggest at least one group of 4 of them!
