How to manage asset pipeline? External Tool imports to Godot or tooling built with Godot

I am working on a pixel arty game and looking to experiment with the DeadCells’ pipeline of 3D into 2D sprites. For Dead Cells they built an external tool to do the 3D to 2D conversion but I was wondering what something like that would look like built into the editor.

Thinking a designer could just import the 3D + animation into the character object and Godot could handle the asset generation at build time. Thoughts?
