It's possible. Perpetual's initial plan was to set STO at the turn of the 25th Century, roughly twenty years after Nemesis. That and considering the fact that the Galaxy-class (and a nice Gen Gal bridge) are in the game so far could mean that we could see not only familiar classes of ships but a couple notable ones, like Voyager, the Defiant, maybe even the Titan and dare I suggest it, the Venture.
