Good idea.
Been reading a lot about architecture recently. Got into it through my already confessed archaeology obsession and think the Big Meg is easily the most cohesively realised city in comics by a country mile, despite being depicted by countless artists (actually Barney might have counted them, but you get teh point).
D'Israeli is a damned good starting point, but how about a few of Mega-City 1's other chief architects (most noteably Carlos Ezquerra) being given a crack at joining the party?
I'm not suggesting EVERYONE gets to have their say, but a selected bunch who've had the most to say and made the most interesting depictions? Just a thought. Marketed right, it could even appeal to the architecture buffs out there (there ARE quite a few of us, honest).
