Did someone say art prompts?
1. Starlights, Starlights, and more Starlights. Girlycard is an obvious Seiya. Timothy as Taiki. Yaten has to be antagonistic to Venus (Seras), so a (sometimes) male Pip who's clad more in the original's outfit (including eye patch). People get him and Sailor Human mixed up a lot...
2. Heinkel as Uranus and Yumiko as Neptune. Haruka gets to be a (partial) male in this one.

3. Millennium as various foes: Doc as Prof. Tomoe, Rippy as Hotaru/Mistress 9/Sailor Saturn (you already did a drawing of this - it's an awesome idea), Major as Galaxia commanding his army of 1000 artificial vampire senshi, and Zorin as Nehelennia. Schroedinger should be the Wiseman for humor, with Dandy as his Rubeus.
4. I wonder if a female copy of Young Walter could be revealed to be Pluto.
The dynamics don't map one-to-one with this, but the visuals are fun. Just imagine Wiseman Schroedinger with a ball of yarn instead of one of crystal.
