I'm not sure it would increase elitism. Elitism comes from organising for the benefit of only the best, to the exclusion of less capable shots. Giving the less capable easier targets to shoot at might encourage rather than dissuade them.
Any grading issues are easy to solve, it's just a change of numbers required. Instead of having a 70% break point to enter A grade from B, you make that say 80% based upon the easier targets that the B grader is shooting.
Going from A to AA can still use the current 80% break point as in this case it's based on the harder targets.
So it's not much of an issue to solve, if the will is there.
