Bad idea, for some reasons:
1) AC changed name once for legal issues, and changing it again without a reason does not make sense
2) It's universally known as AssaultCube, so besides a simple but effective name, there is the fact that everyone who knows it, just needs to type 'AssaultCube' on Google to get it
3) AssaultCube is based on Cube Engine, so the name represents exactly what it is: a game based on Assault built on Cube, so...... No way.
Anyway, QuadAssault or AssaultQuad does not make any sense.
