Pick up only or skip stop service for congested bus lines

Would it work to offer pick up only or stop skip service on bus lines where the end portions don't receive equal opportunity.

Ex: The Bx5. The last three stops before the run to Hunts Point often get bypassed by full busses. Being that there is a school in that last stretch, why not have a pick up only along story ave and discharge at those last three stops. It would make space for elder/evergreen which are the stops that get bypassed at the height of the rush.
