Sacred Haven of Debauchery

Actually, that's exactly what I wanted to say: while Alex is preparing for his campaign, it would be good to think about the format in general. I might even radically change it so that a session in the campaign is no longer than a game of Mafia – short, separate adventures, each time starting from scratch (or with the possible transfer of old characters, but as an exception, not the rule). A maximum of two locations, more often just one. Some well-structured quest that applies to the whole group. A dungeon or something similar... No multi-year shopping trips, nothing extra. The rules can be borrowed from DnD or Pathfinder. And that's it.
The main thing is to do it with passion and creativity, and it will work, and it won't be as stressful as a full-fledged campaign.
Another option is to do it on Discord, as Ples suggested, trying to gather at the same time in the evenings and actively play in a chat format during that time, and then take a break until the next day.
