Well if p-B11 proves feasible, I don’t see why an easier reaction like D-D could not be done. The massive neutron flux from D-D could be used to breed plutonium out of uranium; it could also be used to make tritium from lithium, although what uses would tritium have if D-D and p-B11 are possible, maybe as a RTG fuel. It could even be used to destroy nuclear waste:
