Sounds fun...but no time right now. We'll see....
I actually did two mid-engine Ultima style cars a few years back. They both came out pretty nice, considering they're not really my cup of tea.
Someone drew up a concept of a C5 Corvette with a shifted greenhouse and mid-engine setup. Didn't look as good as it sounded...I'm sure with some serious effort it could work though.
