Would a game that lets XBL and PSN players fight eachother sell well?

I am not talking strictly 360 vs PS3 players.. I mean like shuffle the owenrs in teams.. so 360 owenrs and PS3 owners will be in the same team.. like.. COD but with PSN-XBL link..

 

I think the sales advantage it would have would be minimal if it was not console vs console.
