Just make like 10 different default sets of guns (main, side-arm, shotgun/specialty) and let people choose their set when they log-in. Have an armory where you can change.

Ex:
Marine Outfit - Mp5 Navy, Glock18, Spas-12
Futuristic Firearms - Tempest, Core Handgun, SD Cannon
Army Corps - AR-15, Mini SMG, Neo Rifle
Heavy Ordnance - Gatling Gun, PBP, RPG

Killing people gives you points; you can spend them to get bonus **** like Medpacks (revives), Melee weapons, Bombs, Food, Capps etc.
Events would stay the same; just more bonus **** like the typewriter and supers and instruments and w.e.
Gangs would stay the same.
HP Levels and Killstreaks are fine. Gang bonuses are fine.
Potions would stay the same, they could be bought either with gelats normally or mvp coins, nukes would also cost a mvp coin (this would be highest tier.. for the top players of the weeks + gang events). You'd only need a LW if you buy too much bonus ****.
Money/jobs could stay but would be only for aesthetic stuff like cars/houses/storage/gambling/hats.

**** trading.
**** shops.
**** ammo.
**** businesses.
**** quests.

Zone it up. I'd play everyday.
