I hate to say it, but... No. I'm actually one of the few guys who was able to stuff a G4 iBook into a G3 case (And that was only the bottom half due to different keyboard and display connectors). The only reason I was able to make it work was because the case was the same size and mounting screws were in the same position. The MacBook and MacBook Pros are configured completely differently. Different batteries, the shape of the motherboard is different, the optical drive is in a different spot, the port configurations are different, the display connectors are different, the keyboard/trackpad connections are probably different as well. I don't see how you'd be able to make it work without chopping the case all to bits. You'd be better off making a new case and figuring out how to make the MacBook drive the larger screen. And even that would be a massive undertaking.
