Are you a member of the fan remake team, good sir?
Anyway, the main reason I noticed Milky Touch from other games was its artstyle. It was so good that I thought "yeah it's probably one of these mobile games, with sex scenes locked behind either real money or hundreds hours of grinding". Imagine my surprise - my very pleasant surprise - when it turned out to be a regular visual novel, not a grind toil. The artstyle is the primary (but not the only) feature that sets it apart from the competitors, the absolute majority of which belong to the "cloned DAZ3D botox dolls" type, characterized female characters all looking like Bogdanoff sisters - with giant lips, giant cheekbones, giant slanted eyes, microscopic snub noses, giant tits, giant asses etc. Studio Kuma's characters always had more refined, more elegant looks - they don't look like a washed-up pornstar after her 10th surgery, they look like proper ladies. I think you understand that your sample of the 3D artstyle doesn't really do justice to the originals. I do apologize if I sound unnecessary harsh, but these are my frank thoughts.
I might have a solution, though. Honey Select. It has an excellent character editor which is capable of producing what I would call "refined ladies":

I'm not sure if it would be easier to make static poses there or in Blender, and I'm pretty sure it would be an issue to find HS backgrounds corresponding to the Milky Touch backgrounds, but I still would propose to you guys to at least consider Honey Select as your "engine", before you start the development.
Milky Touch doesn't deserve to be reborn as a generic run-of-the-mill 3D mediocrity.
