Hi! Yeah I agree I'd love to have unique graphics for the tiny assemblers, sadly it's a bit tricky at this scale and I'm not too graphically inclined. If you know of another mod that has graphics for small assemblers I can use (IR3 does not permit using their graphics, so they're respectfully off the table), let me know and I can look into adding it! I may also try my hand at modifying the existing sprites to kitbash a convincing tiny assembler, but no promises.
And if you want I can add a setting to remove their module slots!
