Help converting game from 2d to toon rendered 3d models? (8-bit)

Hello everyone,

I am working on a small game, and it is very hard to add new content and manage server, etc; as a one man show I was wondering if I could perhaps convert my character model to 3d, and make use of all of the wonderful 3d assets out there.

I have attached a 2d gif of the current model, what would be the best way to go about this? I was hoping there might be an easier solution than what I anticipate, looking for any tips, keywords, or where to start. Thanks in advance!

I should note, I have played around with some models and tried some toon rendering, but I was never quite able to replicate that 8-bit feel.

Do NOT think its possible somehow “easily” cause 3D bones with IK does not feel 8-bit. And as a cherry on a cake I also think that modelling of this kinda stuff will not be easy at all… U need that “person” model?
