If your players are experienced, I would opt for troupe style play, where each player can have 2 PCs, one as a decision maker/bridge crew, and one who's a junior officer or crewman. This makes it easier to include all the players (w/o including all the characters) in each missions. It also allows for all that lower-decks fun we all like
, and makes the ship seem even more of a family and home.
I can't say I'm thrilled with the whole crossing Romulan space thing for any number of Trekverse reasons, but... If you're going to use Reman shocktroops (which we actually saw in Enterprise!), you could set up a scenario like one we saw in Voyager as they cross Romulan space. I forget the episode name, but Voyager was crossing the space of the species who hunted down telepaths, so they had to agree to periodic inspections and were forced to hide the telepaths. In this case, the Challenger would be forced to travel from point to point, and submit to inspections, carried out by Remans, looking for you name it... yeah, I don't think it's great either.
This is one of the issues with the NX-era. You can't easily use so many of the established species as major ongoing antagonists.
How about they don't really need to cross all of Romulan space, just reach a certain point within their space? Because there's some wormhole/anomaly that could get them much closer to home, or take them back in time so it never happened. My friends would love the RP of that - going back to where they were a year before. And remember, there's no prime directive or temporal prime directive as of yet
If players really wanted to play non-humans in Starfleet, they'd really have to justify it to me, with a little more slack for Vulcans. That's me. Obviously, if they're not in Starfleet, but are on board for some other reason, it becomes easier.
