I don't like it, because thinking player should be calling the river with most pocket pairs that he called the turn with (55-JJ).
Main reasons:
1. it is hard for OP to represent big pocket pair after checking the flop, because everyone (and probably also OP) is betting their big pockets on flop to get the money in before scare cards (J,Q,K,A) come on turn/river.
2. it is hard for OP to represent 6x, because there aren't many 6x hands in OP's range after raising the limpers preflop, perhaps A6s, 67s, 56s. It would be much better if it was an open-raise without the limpers, then OP could represent 6x better. One does not put an unknown on 6x when the unknown raises limpers, they think strong pockets/face cards. But all face cards missed, so they hope you have AK and call you down with TT.
