If the option chosen involves some way I can sporadically contribute content, I shall likely toss my art in when I've the time
As a suggestion for pulling off Option 3... in the first campaign my group held, our Glorious Solar PCs ended up with a particularly nice Factory Cathedral, in which we lived along with ten Dragonblooded, three Lunars, one Sidereal and one Abyssal. After that campaign ended, we went on to other games, but in our free time the ST (Anomaly0.01, who just signed up here) and I often joked about adding other characters to the Factory Cathedral, coming up with stories about them moving in and adding to the campaign's canon. Many stories were devised, sometimes semi-serious (adding a Lunar from elsewhere as my Solar's mate) and sometimes just silly (moving an evil Infernal into the Cathedral.)
Anyways, my suggestion would be coming up with some sort of setting that could be a starting point for a wide variety of stories. Perhaps a Cult of the Illuminated city that openly welcomes Anathema, or a specific kingdom, or even a seedy bar in Nexus where an odd knot in the Loom of Fate keeps drawing in really important, Exalted customers to the point where the owner has just gotten used to it, or whatever. Something half serious, half silly, and 100% plot-hook-y. Artists, writers or artist/writer teams could then insert their characters into said setting, writing separate stories but making reference to the events of other stories set in the same place. There could even be submissions, of both comics and stories, with accepted submissions becoming "canon" for the setting, creating a sort of continuity.
Just an idea, hope it inspires someone
Whatever option is chosen, you can be sure I'll be reading the comic!
