Obvious action items:
-Produce flatbuffer schemas to add new animations.
-Produce converter from BCH to GFBMDL, to use USUM models (no converter exists right now).
-Upscale old pokemon textures. (seems done)

Sorry please delete this

Some people made an HD texture pack for USUM couple of days ago. Some of these textures are upscaled, while some are enlarged an sharpened.

ScriesM has done it, he's imported (Rather easily) a unique pokemon into SWSH

It seems upscaled textures have already been done 

Things left to do according to him:

Obvious action items:
-Produce flatbuffer schemas to add new animations.
-Produce converter from BCH to GFBMDL, to use USUM models (no converter exists right now).
-Upscale old pokemon textures. (Seems to have been done)

Someone tried to do imports using Blender, according to some, however, Gamefreak uses Maya, this might be the cause of the issue he has.

"As far as I've seen. Pokémon lets go models are the same than USUM (You can use same rigging and textures). However, SWSH meshes break when importing the rigging."
