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.

Astrosmash, so your saying the sales difference would be because both sides want to fight some battle out? I doubt any developer would want to make that..

 

I mean a game that just lets friends who don't own the same console still fight together

Think about this idea... Why would SONY or MS want this?
