Here's an idea.. on the PBW server replace all the texture images with a small 32x32 white (or any color) image that takes very little space.
run a batch program to rename and copy the PlaceholderTexture.bmp to the target mod folder.
I attached a small 32x32 white .bmp to this post. (It's 4k in size)
That's the only 'workaround' I can see. and it would most definately reduce the amount of space taken up on the PBW server.
another way would be to batch 'scale' all the images in the mod folder to 32x32.
Just an idea from an atrist's point of view.
Cheers!
