Imps have more cc? Mirror classes, same amount of stuns/cc. Also, if you want to nerf Sorcerers, then you want to nerf republic sages. Keep that in mind.
Sorc/Sage hybrid spec needs to be looked at, has everything with virtually no drawback. I'm guessing since they killed Assassin hybrid spec, they'll eventually get around to Sorc/Sages. Until then, worry about more important and game crippling things, like population balance and all the bugs that plague this game.
