Caution, I am not familiar with some of the points transfer strategies. however, you might try moving your points from US Airways thru a hotel program and then to UAL's program. As an example (perhaps poor), Amex doesn't allow conversion to AA miles. Recently I moved Amex points thru SPG to AA to pick up 50,000 miles. Not sure if it was very efficient or how your math might work, but you might try some combinations.
