I recall Randy looked into these sometime ago and determined it just wasn't cost effective to make a custom display (the current notebook size used wouldn't fit the entire large sega screen). Unfortunately these probably won't happen so you'll probably have to look for another solution.
Quoted from Taygeta:Has it been said one way or the other if the large Sega DMD games (Maverick, Frankenstein, Batman Forever and the best pinball machine ever constructed, Baywatch) will be supported by ColorDMD at some point?
