I don't like limping. Ever. Not going to say that it wouldn't work for you or anyone else but its not my game. I prefer to play strong and limit who gets to see that flop. Easier to put people on ranges rather than any two cards that would call the BB.
Even when set mining I'll never limp. Open and fold to 3 bets, and with no set on the flop we can sometimes make the cbet in position if the flop looks right. Again, I'm always trying to make sure fewer people see the flop to avoid those straights and flushes.
If limping with a monster is even a question I think you should look at what your standard opening range looks like. If you open with pairs, AK - A10, mid suited connectors and up, then your AA standard opening raise is just as disguised as you think your limp is, just without looking weak and allowing multiple people into the flop cheap. People are still going to try to 3 bet and get a piece of you without deliberately making yourself look weak, from my experience.
When my AA opening raise gets folded down and I collect the blinds honestly it doesn't bother me at all.
