Yes I would love so much to have Codename Sailor V as an animated prequel. I would prefer if they adapted it to the 90s canon but I would still be fine with and like to see Crystal do it. Especially so I can see what many of the villains look like in color. I would also like to see Parallel Sailor Moon be animated to see what the Parallel Inners look like in color.
I am with you on most of the ideas. A Chiiusa / Sailor Quartet centered story, I am all for that, or at least for a good chunk of an arc, like Gohan at the beginning of the Buu saga. If that happens, I want the Quartet to have some sort of special relationship or what have you with Hotaru aka Sailor Saturn, for all intese she saved their lives. If it wasn't for her, they wouldn't be alive.
A Codename Sailor V adaption, some of the side story getting an adaption.
