flop call is fine. set outs+backdoor draws, and you're ahead a very small % of the time when button is raising a flush draw.

on the turn you're turning your hand into a bluff vs button. based on your read if you get called you are dead even if a heart comes off, you're drawing to a 9 only. if you get reraised, you have to fold. if button calls your c/r, you have to fold a non-9 river.

heads up I think that if will actually fold all those QX hands (unlikely IMO, but you say in your read he probably will) the bluff is profitable. you are getting ~5:1 on your bluff and JQ AQ no heart makes up more than enough of his range (I put his range at [JQ KQ AQ A9hh-AJhh]).

having utg+1 in the hand makes it more complicated. but as you said, you're ahead of him a lot and you usually have outs if not.

meh I think it is OK the way you present it. I would never make this play though because noone in my games would ever fold a Q there.
