Have Denise Crosby's and Tom Hardy's Romulun/Reman characters answer to Tomalak and make them a combined nemesis. Instead of Picard getting tortured as always (assimilation, "there are 5 lights", etc.), this time he's captured and from afar has to watch his crew tortured. More than 1 cloaked predator ship. Some post-Dominion war story arc. Have Shatner and Nimoy there. The emergency command hologram on a ship goes offline and Spock whips up a new download with Captain Kirk as the ECH. The Klingons end up occupying Romulus, ties into the new movies. Something like that. Sequels, shmequels to everything. Write new stuff already.
It'll probably be good, though, Stewart can carry the load onscreen.
