On the dune, I had exactly the same attack (4-hi, traction control off) as with the RR lift and SilentArmors which never gave me a problem on the same dune (and put a lot of JKs to shame!). I see three things adding up to create the problem. First, going from 30" to 33" tires. Second, going from an AT (fairly closed tread pattern) to the BFG M/T KM2s which paddle like crazy. Third, I aired down to 18 lbs (same as I did with the SAs) but with a 33, I may need to go down to 12 lbs to get the same float. The problem was, I couldn't get up on the torque curve and just ran out of power (and yes, it is the Hemi!). There was a lot of other sand on the run and it did fine, though not as well as before the new tires.

Neil, the Mickey Thompson 265/70s should be fine IMHO (unless you really need that extra 1/2" of clearance).
