I had the idea today of starting the game on New Caprica, rather than ending there. Then, after the NC phase, the game continues as it did in the original version until 7/8 distance +1 jump.
The Cylon admiral is an issue, so I'm thinking rather than an auto jump, his ability activates a skill check that must be passed to jump away. Something like Green, Purple, Red and the difficulty is equal to the number of civvies still on the surface. Also, I think that some of the civvies shouldn't be on the NC board to begin with, maybe put 8 ships on the board to start (in the show, there were a few ships that jumped away with Galactica when the Cylons first showed up).
I've not tried this yet, but I'd like to hear thoughts.
