What if the WGP racers got involved in the fight at the end of Cars 2?

I really love all the World Grand Prix racers, and one of the things I wish we got in Cars 2 was learning more about them. And since they were the ones most affected by the lemons’ scheme, I think it would’ve been cool if they all teamed up together to fight the lemons and give them payback for what they did to them. And it would give them more purpose than just being crash dummies.
Seeing McQueen and Francesco teaming up to achieve a noble goal would be great character development for the both of them, putting their differences aside to fight for what’s right. And seeing them and the other racecars smash the lemons would be awesome and satisfying.
