I've wondered in the past whether BA might try and pick off some low hanging fruit (no disrespect) in terms of licenses. If they can get Australia and England then there are other nations that might be possible to get.
The cost-benefit might not be huge and logistically it could be difficult. Although given most of the best players in the world are going to be in the same area soon (plus Ireland, Scotland and Netherlands), who knows. Of course, implementing them (appearances, kits, stadiums) could be difficult without expanding.
