Sorry mate if you thought I was going off-topic, I was merely suggesting that it would be cool to see custom player-made billboards on the server.
In regards to your suggestion of having specifically the BCS billboard, I just don't think it would be that useful as more than a one-off joke.
It would be more far more engaging to enjoy player's creativivity and letting them make their own billboard graphics (which they can pay for within RP and use it to advertise their services) rather than just having a null texture that doesn't refererence anything actually happening in the game.
Just my two cents.
Like yeah if a player wanted to play a lawyer who was similar to Saul then that would be cool, and they could edit the billboard you suggested in their own style maybe with their own player model and their actual phone number, then yes that would be sick.
