[A Song of Ice and Fire/Game of Thrones] Before Robert's Rebellion, would Tywin be content if Cersei was betrothed to a hypothetical older second son of Aerys II or did he really wanted Cersei being paired with Rhaegar?

Dude wanted the throne under a lannister thats all. If there was an older Targaryen then he would want her married off to him. 

Im sure he would settle for a second son and the lands associated with it but its called a game of thrones for a reason.
