Possible swap or too "far out"??

I was just thinkin bout the ecodiesel rams today and had a sudden brain fart... Think anyone will attempt to swap the 3.0 into a classic Mopar?? I think it'd be really sweet!! They only weigh 50# more than the 5.7 Hemi and get 27 highway mpg in the trucks (the founder of hypermiling actually got 36 out of one!!) they'd probably top 30 mpg in an A!! Or is this a sign that my brains are about fried......?
