It might work best if the writer types put together a second project - I love a lot of the art ideas that have been suggested, but it's hard to interpret in writing.
Writing could be...
-bite-sized (300 words or smaller?)
-SSSS-related obviously
-Would probably be best to have some kind of theme to link it together, so maybe exploring the setting/worldbuilding through the canon characters? Or with original characters?
What do the writers think of the idea of the above, doing something that's "together but separate"?
