Yes, makes sense to me.

I think the main things to worry about are:

1) Sacrificing some AA equity. I'd go with a lesser raise personally rather than pushing--at least if you can also throw enough in there on the push to prevent 22 from calling.

2) Tight raisers. On that one, I think 10% is probably about the point where it becomes roughly break-even rather than actually profitable. But as long as you're on top of who the players are in LP, then you're good to go.

3) The QQ-JJ issue, which is probably actually related to the question of tight raisers (as well as stack sizes). If you have the full 20% of raising hands, then you figured something like having won 60 or so BB before you ever even get a call. With your numbers (where JJ still calls a lot), I'd guess QQ is still profitable at stacks of 100 BB, but JJ probably isn't.

Another factor to consider on those is how much you will lose with them as overpairs to AA/KK anyway. If you bet into the raiser in a pot of 13-20 BB but fold to a raise, then you lose 20-25 BB anyway whenever LP raiser has AA/KK. And you also may end up laying down to something like AT on a T-high board. I don't know how you guys play those hands 6max, but folding to the first raise may also not be the way to go in that game. If not, then you're going to lose quite a bit anyway (possibly a stack) when you have your QQ overpair and LP has AA or KK.
