After the flop bet, I put him on 9Txx, a 15+ draw, two pairs or a set (but since he bet into the whole field, I do not expect to see 2 pairs or a small set very often).

Unless I've done something majorly incorrectly, it looks like you are a pretty big favorite to his range on the flop, enough so that it might be a clear re-raise on the flop.

It does get pretty complicated though breaking the different outcomes to your reraise, i.e some of the time he folds (and you have FE) and other times he reraises with a better range of his hands. I don't immediately know how to calculate the chance of each hand type of his range being in his hand. And I agree with you that the downstream analysis is necessary.
