I had this stupid idea. I was just curious on how it'd work.
A "C&C Game mode"--Obviously not the exact same thing, but something similar.

Based on C&C Renegade. An FPS from 2001 (or '04) based on an RTS that came out in 1995.

It was fun, but I was just curious on how TF2 would work with it. It was a class-based game that you would have to "Buy" classes with "Credits" that can be earned from killing buildings, people, etc.

Gameplay (Yes, the guy has skins. The original game looks somewhat better)

Just a thought. I know it wouldn't work. But, it'd be funny.
