There is already precedent for this: HA offers cards from both BofA and BofHi, Hilton AMEX and Citibank.
That said, the Aadvantage program is a BIG profit center for both AA and Citibank, I would expect the latter to fight hard to keep it all, Barclay's does not have the bandwidth, resources to go it alone, would have to invest to participate at the higher level.
