Once you make those assertions, why would we raise AA-QQ? If we didn't, they would certainly add some teeth to "iso-raise me at your own risk."
i think you are making a game-theory case for in fact at times raising the the other hands an appropriate portion of the time, or as you say, ALways limping in ep. this is assuming your opps actually pay attn to your opening requirements by position. i think this thread of thought is more suited to short handed play.

SS1 advocates limping your monsters early for the very reason of being able to limp your other hands with the omnipresent threat that it could be aces.
