This is already possible, but...
You first need an anime style head and body morph. Then you need an anime style skin texture. There are some around in the community, but you have to dig deep.
BUT: It will look more like in Honey Select or Ai Shoujo, because you have no custom skin shaders in VaM at this point. To get a look like in Koikatsu or MMD, a custom "Cel Shade" skin shader would be needed. This will be possible with the future VaM 2.0.
I did many tests. It is somewhat possible, but it will be quite a bit of tinkering and it willö never look absolute perfect. Once you have the look, you will need anime hair styles and clothes... aso.
VaM can do so much much more than only anime style, like in the games you mentioned. Unfortunately therefore it is much more complicate to get such a special look, than in the games which are specialized on this (and only this). No click-and-ready in VaM, except of user made scenes.
If you want to go go deeper, then I suggest to visit the NoOC VaM Discord channel. Lots of anime and game-style stuff there, but also technical discussions and some tutorials.
