Not really feasible. Time margins are extremely narrow in this phase, there really is not the time to review the multitude of launch footage taken from a variety of angles in order to find an unlikely event that would enable you to make such a dramatic decision again within a very limited amount of time left. For the decision to make an abort, very definite and certain criteria have to be met, that's a really tough decision in itself. Also you wouldn't do an RTLS, both because of time constraints so early in the launch (there simply isn't the time to perform such a review while the stack is within RTLS range) and because it's the worst-case and most dangerous abort mode there is (that is, there's a chance the orbiter doesn't survive), only to be used in i.e. a very early double engine failure scenario. If an abort based on such a review would be made, it would be ECAL or TAL. CU!
