Anything is possible in theory, if you're willing to throw enough time, money and circuitry at it.  But I'm going to make a wild guess at "not easily".

The recipe for the UglyMac and other clues about the place suggest that the video output from a b&w compact is roughly the same as PC-world EGA in terms of timing.  One of those, you would want to check for yourself.  If you find a nice big monitor that matches timing-wise, you miiiight just get away with a little circuitry in between to make the sync and signal polarity match what the monitor is expecting.  But plug and play?  Nope.
