Gabriel, do you mean pollinate several blooms on one stalk with different pollens? That may put undue stress on the rhizome to produce that many pods. I think I would limit it to one bloom per stalk, but several in the same clump should be okay I think.
John, while one could pollinate a single bloom with pollen from multiple doners, you wouldn't know the parentage of any seedlings that you liked. Crossing the same 2 that have resulted in a previously introduced variety won't produce that variety again.
