You probably don't want to do Baltimore to Sf and then SF to HNL because it'll be 50k per person (25k per each leg). If you want to do business class, it'll be 75k from SF-HNL alone since AA (and Alaska too?) classify this trip as first class in the two cabin configuration, 3x the Avios. It might be better to try to do UA or AA miles since it'll be less miles (although you already have the MR points, so could use them for this, but the Avios are more valuable for other trips, esp short hauls to Canada, etc..).

Maybe do AA over via Dallas so you can get the international business class product and UA back with a stopover in SF (if UA allows stopovers on one ways).
