Don't you need a lot of different colours to implement FSAA? Since you're blending the surrounding pixels to hide the jagged edge. The visuals already seem to be doing some sort of antialiasing anyway but you'll have to ask Toby as he's the guy who knows. And my knowledge of antialiasing techniques is crap to say the least.

You can't have full greyscale for reasons listed here. I think somebody mentioned that you can get possibly 1 or 2 more levels but they weren't that good.
