You can combine USAir and AA (if you have any) miles to claim an award on either. Of course, IF(and it's a big one)the UA/US deal goes through, then you'll have 16500 UA miles. Are you in AMEX Membership Rewards? In lieu of a lot of magazines and possible point dilution on transfers, you could transfer sufficient AMEX MR points to CO, TWA or US to claim an award on them. Or, if you have a Diners' Club card, to any of your orphan mile airlines. If you don't have a DC card, not long ago they were offering 10,000 or more miles for new cardholders, and perhaps you could get the deal.
