The characteristics of He3-He3 (cross-section, reactivity, Lawson criterion) are at least an order of magnitude below those for pB11. (There is a graph of reactivity on p. 7 of this presentation.) In addition, He3 is hard to come by. There might be some circumstances where the He3-He3 reaction has advantages over p-B11, but I don't know what they would be.
