If down the line this model could create 3D model from 2D images that would be very neat way to pay less for war gaming models

Gaussian splats and neural radiance fields already exist.

You can already do this with apps like Kira. I believe it is especially good on the iPhone variants with LiDAR.

Already done. Cults generally has stls of 40k models before release. Its just a matter of finding them.
