Just to provide some specifics about the "laundering" through the HHonors program, here are the links:

The bottom line is, you would receive 2 HHonors points for each UA mile. (Transfers are done in increments of 5,000 miles.) Then, going from HHonors to AA, the exchange rate is 5 HHonors points = 1 AA mile, unless you exchange 50,000 points, for which you would get 12,000 AA miles.

So the BEST you could do would be 25,000 UA miles = 12,000 AA miles. Otherwise, it would be each 5,000 UA miles = 2,000 AA miles.
