Again, thanks all for the advice. Seems that you have understood my dilema perfectly. I think I have a few options really:
Announce Outcasts and just accept that everyone knows pretty much who I'm going to be selecting.
Announce Outcasts but have a second option to Ophelia. It does mean collecting a couple (or more) non related crews and pciking the best one for the job which I suppose is pretty correct for Outcasts as they are the merc and otherwise dissowned faction.
Annouce Outcasts and select from all the gremlins. This keeps me 'green' and gives me a bit of choice but with my dislike of Somer am I actually ever going to pick him over Ophelia? (to be clear this dislike is not based on on his model or any play testing I just don't really 'get' the whole Somer thing like I do with Ophelia. Background and picking stuff I like is important to me when deciding what I want to play)
Announce Neverborn and include some kin as an option if I pick Zoraida. This is the path I've already got models for and allows me much more choice (as I can go any Neverborn master and like other factions there is more scope for using thier stuff for different masters). Only real down side of this I guess is that it's not a gremlin crew and I'm limited to how many LaCroix Zoraida can take. Just feels wrong to be announcing Neverborn when I want to play Gremlins!
Perhaps this is only an imagined problem and as I get more experience with Ophelia I'll be more confident of completing the different strategies with her and not worry that my opponent knows that he will be facing small, green, slightly inaccurate, cowboy impersonators.
