In case the title isn't clear enough (probably isn't), I mean 8x modter with textures to make it look like a tiny 64x modter brick. That is, it has 8x8 prints on each face (or less if it's a shorter face, obviously). Essentially, just shrink the 64x modter bricks.
The reason: making models to fit more stuff into the render distance for a video project without needing to use blank textures.
Can already do this, but, as you can see, it relies on blank textures to work:

With this, I'd be able to do miniature terrain, so that I can build mountains that look convincing without running into the incredibly-short-when-trying-to-make-huge-things render distance.
Edit: found a far simpler solution: make new textures instead.
