"Invisible" perk and crowd gamemode?

[dm.mossberg590a1]

I'm thinking about a new perk (a combined perk) that allows the player to use the "invisible" skin like when a player spawns which makes it harder to see him. Of course people with the Recon perk can spot him out quickly. The drawback is that people with the perk are slower and firing makes you "visible" for two seconds.

I'm also thinking about a new gamemode where people of different teams are randomly spawned everywhere all with the same skin and bot "civilians" are also spawned randomly. The goal is to find and eradicate the members of the other team with the least civilian casualties. The "civilians" would be running around with knives (not using them though). Both teams would have to blend in as much as possible like holding a knife and secretly eliminate the enemy team (for example no gunshots). If you try to fire a gun or make a sound near a bot, bots nearby who "heard" you fire will try to knife the closest player (the default behavior for normal bots once they hear a sound).

What do you guys think?
