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.
