Feeding pinkies or not feeding anything is about all the same.
Can you do it? Sure. Will it work? Not likely at this size your BP will not likely recognize this as a prey.
Pinkies are nothing more than blobs of water & fat with no real nutritional value, the bones are not properly formed (calcium deficiency), there is no fur etc
A hopper and 5 pinkies are not even close to a proper meal for an animal that size.
