TF2 Style Class system for Multiplayer

What about some DLC? Downloadable Content. This soldier will carry any rifle... idk, call him HeroOfMany. Hence a HOM unit.
H.O.M

HeroOfMany:
Primary:Sniper, Rifle, Shotgun, ETC. (All Primarys).
Secondary:Pistol, SMG, ETC. (All Secondarys +Silencers).
Melee: Any animation (Like how spartans Assassinate).
Special Weapon:RPG, AT4, ETC. (All Heavies).

IDK its just like a Supersoldier. what do you think?
