You realize the only air in your range here for betting the turn is AQ/AT/QT/Q9/56 right?

AQ and Q9 are the only ones that don't have a straight by the river.

I just don't think a bluff range that small needs a hand like J9 here to merge in order to be balanced.

If you are so sure he'll bomb the turn if checked to w/ weak SD value but unsure of what to do on a lot of rivers, I'd prefer to do something silly on the turn like bet 80$ or even smaller in order to induce him to turn some of those hands into bluffs so that I could then shove over and he'll sit there feeling owned really often. The other benefit to this is that if he just calls, your river situation is much improved and it's much less of a big deal to fold since the pot isn't nearly as big. (Also his range will be well defined as quite weak if he just flats).
