I dont think so... not finished looking yet. Interesting post though. For the time being it's the best proposed idea.

320x256 lines = 8,192 bytes to display a screen - a nice 'round' power of 2 number and easy for computers to handle.
Erm, 320x256@1bitplane = 10,240 bytes (10Kbytes)

COPPER video timing display is 8 bits, so maximum of 256 possible values.
But as you said you just combine waits to perform overscan...
