Is there any reason why someone couldn't create a board that would
bypass the Mac's current video circuitry so grey tones could be
displayed on the existing internal CRT?

Correct me if I am wrong, but this shouldn't be much more complicated
than the schemes that allow a Mac Plus to use a large CRT. It might
involve replacing the existing analog board and using a clip to the
68000 to bypass part of the Mac's video management hardware. 

This would seem to be be a very, very popular product if someone could
pull it off, especially since the Mac II is creating a standard for color
and grey tone software. I for one would like to encourage others to
create an upgrade path for Mac 512/Plus owners since it doesn't seem
like Apple is interested in this market.
