I think it's a bad idea. Why take a support or a sniper if an assault can have an LMG or a Sniper? No, clearly, it would destroyed all classes and make battlefield even closer to CoD (a game with no real specified classes)

Moreover, with some cleverness when your choose your weapon, you can barely do what you say.

For example, in assault class:

Sniper style weapon:

G3A3+bipod+x6, Scar-L+Bipod+x12, AN-94+Burst mode+Patience and Practice (AND NO FOREGRIP)
