You shouldn't really consider improvement cancelling each other out, as

1. You're drawing dead against AA
2. I don't know what your action may be if a K drops on the river, I'm guessing you can c/f.

I also wouldn't count JJ for the full 6, a preflop cap with JJ doesn't happen all that often. If he calls the turn and you improve on the river, then you can probably 95% put him on JJ or KK, I don't think AA is going to wait until the river to raise. I just pointed that out, I'd put him as doing that probably 5% of the time maybe. Now AK could perhaps call the turn and river expecting a chop or a loss to AA, but you've got 6 instances of AA, and only 2 of AK, which I'd say is good. All in all, I think improvement favors you. Even then, I don't think it'll count more than 2% of your EV, and I don't see KK dropping this more than 20% of the time.
