OK, just for the purpose of the discussion (I think there are few things to develop)
you still want to have 3 bet bluffs in your range, so I guess that you will include a lot suited aces and even some suited connectors in your 3 bet bluffing range?
Also, by definition, bluffing means getting folds from better hands. IF vilain adjust properly to deep stack play, he should call very wide here, so I am wondering what better hand can fold? Yes, if you 3 bet TJs you can get a fold from KJo, KTo type of hand that have you dominated.
If vilain don't adjust correctly to deepstack play and still fold as much, then I think we can continue to 3 bet bluff him all day long.
In position it would be a whole different story tought. We can still continue to 3 bet bluff a lot and can make it 9$ or even 8$ if vilain folds everytime. (make our bluffs cheap)
Also, I don't understand why you would like to bet smaller with a big hand oop? If vilain want to call with a wide range isnt it the best opportunity to make him pay the price for it? (I think that we are likely ahead pre with AA
)
Also, there are other factors that could be considered in our range construction, like how we think we can outplay vilain in a 3 bet pot oop (do we have a hughe skill advantage or not)
