I'll take a look. The 3x3 ones from that mod would be easy, but it'll take some new logic and graphics to handle 2x2 and 4x4 (short of just jerkily upscaling/downscaling). I've been thinking about converting my graphics to 3-panels wide, rather than 4 so I can more easily support 1x1,2x2, and 4x4 panels that look good next to each other. I really like how Bob's did that.
