The gatcha game seems pretty easy to make from a programming perspective. It would require quite a lot of 3D modeling though, and would run into licensing issues unless you made up your own IP
One workaround that comes to mind for the modeling thing would be if the characters were all androids or something. So they'd all have the same body base but with varied proportions and then their head would just be a 2d screen with a face. Cosmetic changes that require additional 3D modelling/animation could be added later as in-game purchases.
Besides that though, for VR where people are expecting high end experiences unlike with casual mobile games, a lot of resources would still probably be required to have compelling story/gameplay/characters especially if not working on an existing IP.
