I think three great Federation ships would be the USS Relativity (the future ship from the Voyager series), the USS Pegasus (from The Next Generation series) and the Yellowstone Shuttle Class (From Voyager).
A ship for both KDF and the federation could be an Alice shuttle (Voyager series) that had neuro-mematic controls, it allowed Tom Paris to control the shuttle with just his mind. In the game it could have great maneuverability, speed and an ability where most shots taken at it are missed.
I think the alreadt came up with that in endgame episode. you see admiral janway controlling her shuttle and it is even mentioned by the doctor and the admiral.
"According to John Eaves, the Enterprise-E was to have been retrofit at the end of Star Trek Nemesis but due to budgetary reasons and script changes the Enterprise was only seen being repaired in dry dock. "For the end of the film the badly destroyed and damaged E is being rebuilt in space-dock. This is where the opportunity was given to really fix all the lines and flow to match the roots of where the original drawing had left off. Not too often does one gets the chance to rework a beloved piece of art, and I was so happy to get the chance regardless of how minor the changes were."
"The drawings were done and to be seen as the E leaves the space-dock at the end of Nemesis, with what we were hoping to get approval on being the new aztec patterned paint job, that was so prominent with all the preceding variations of the Enterprise. As production went on, it was becoming clear that Nemesis was going to be the last of the TNG movies and thus, the E would fly no more. Very sad thoughts, and I was so hoping to at least to get to see that final version fly off into space… Budget and script changes kept the E in the bay under repair so all that exists of the big finish only exists on paper as a bunch of plans."
How about some costumes for customizing the shuttles? I just mentioned in another thread how I'd like to see an Intrepid Aeroshuttle costume, and maybe a Nova Waverider one. There's dozens more shuttle types out there that can be applied as costumes to the existing shuttles, rather than make whole new ships...
I'd like to see the Ambassador prototype as an additional skin for the Ambassador class. The Merian class is, like Vesta class, from TrekLit and featured both in the VOY relaunch novels ("Children of the Storm") and the SOTL 2012 calendar.
