I think you already do 2 to a degree and if you are asking that question maybe need to do it more?

The drawing hand bit makes some sense becuase I think your right but if you stick someone on AK/KK/AA, someone else on KQo and another on 98s the odds go 54/17/28 (in pokerstove). Playing KQ against a tighty means if I hit I am still not always happy. But you are right in saying your implied odds can go down a fair bit with drawing hands against a tighty. Not sure how I actually balance these ideas in my head.
