Make a buyable Cyanide Pill that when taken will kick in after 5 Minutes and PK your character.
Would suggest like putting it on Sewer NPC for like $100,000
I'm not sure why this isn't a thing but just doing a (for example) /itar to speak Italian through radio so everyone and their Mother can't hear what anyone has said on your radio channel. I would assume this wouldn't be too hard to implement.
Bring back the Leprechaun's Winklepicker bar as there can easily be 2 bars in the city. (P.S if it happens its mine x)
Also lowkey miss renting World Corp offices was nice to have a good view of the city not really any buildings give you that now
