Is it feasible to run a one GM-to-many players RPG over discord to keep the server active?

background: I have a discord server (not RPG related) with about 10 people and the activity is quite low so I would like to boost that. secondly I’m quite interested in RPGs in general and am happy to be GM in a play by post game.

idea: to run a one GM to many players RPG where any of the members can contribute to advance the story and everyone posts asynchronously. the players would have to be comfortable just following the story and contributing whenever they feel like it and letting others advance the story at other times. i’d GM, tell the story, and occasionally do mechanical things like dice rolls.

question: do you think this idea is a feasible one? what are some possible pitfalls in such a game? Would you recommend a shared lead character that all the players roleplay? what systems would you recommend? are you aware of such one-to-many games being run on discord?
