I looked back over some of the documentation just now - if I'm not mistaken, Copper MOVEs take 560ns (four cycles) to execute. Running with my true-color idea, that would make a bitmap of 80x(screen height) theoretically possible, though I don't know how stable it'd be in practice.
You could also use DynamicHires, changing palettes per scanline, still gives very nice results, at a decent resolution. Several art programs will output this mode (HAMlab, ADpro and, I think IFFPro on the PC). I'll find some examples in a bit.
