Bear in mind the difference in midrange response could be more a guitar thing than the pickup - I would never expect a Strat to have midrange equalling a Les Paul acoustically, and the pickup can only respond to what the guitar gives it.
I've got an alnico Nailbomb set in my Les Paul Custom atm, and yes it's a middy guitar to begin with, but I'd never describe it as feeling or sounding like an SD Custom 5 (a pickup I also dislike). I recently sold a Strat that I've never got on with because no matter what pickups it had in it, it sounded thin and twangy, which would be great if I were a country player but I'm not! Even Warpigs sounded thinner than they should in it.
So the moral is just because you didn't like it in your Strat doesn't mean you won't like it in a completely different guitar. I've had pickups respond very differently between different Les Pauls, let alone something as different as Strat to Les Paul.
