Quite honestly, I think a sprite comic, unless handled expertly or not being based on humor, would do less to help the Compendium than it would to demean it. Especially if it were based on the Compendium itself--that means not including people from the Compendium. Besides, I don't think Zeality has any one particular sprite to represent himself.
And more to the point, if you put in Compendium people, we'd have a bunch of newbies who hang around trying to get put in the comic, and then we'd either have a bunch of whiny 12-year-old brats who resent that we have a selective casting process or too many generic and flavorless characters that we'd know what to do with.
So, while I don't exactly approve of doing any comic in the name of the Compendium, if you're still determined to do some sort of comic, I'd suggest finding an independent place to host a Chrono Trigger-based comic. In that case, I would also offer my hosting services.
