I doubt Larry Kaplan would do any programming for a new Kaboom game. It would be great if you get an idea together for Kaboom 2 and submit it to Activision.
It would be nice to see a game like that for the gamecube but Nintendo would probably never go for it. The main problem I see with your idea is that it doesn't seem like there will be much bomb catching going on. The magic behind the original Kaboom was that you got sucked into the game because it was addictive (zen). I think a Kaboom 2 game should basically be the same concept as the origional. If a Kaboom 2 was actually going to be made this is what I think the requirements for it would need to be for it to be succesful..
It should star the madbomber.
The main part of gameplay should be catching bombs.
The graphics and sound for the new version should be updated to todays standards.
The game should be comprised of different boards. Ex board 1 the madbomber is trying to blow you up in New york. board 2 he's trying to bomb you on the ocean. Board 3 he's in a space ship trying to bomb you on the moon. (these are just examples that would make the game more entertaining to look at while you play)
The game would have to be released with a new type of paddle controller. Kaboom can simply not be played without a paddle style controller.
Anyway
I like your idea about teaming him up with the dude from Keystone Kapers. Perhaps the could work as partners bombing stuff on different levels. The begining of the game could be a short story of how they both went to jail for a few years and are now planning on taking over the world together. :-)
I definitly agree though that Larry Kaplan and David Crane would have to be top consultants on the game.
