It would be pretty nifty if you buffed the hell outta the titans, but then made it so they need commanders inside to power them. I think this would give even MOAR weight and importance to the titans, and moar risk/reward when using them. These titans already have neato powered down poses and powering up animations(or at least the atlas does, I don't spend much time looking at the others except for ares, who is a spiky brick)
