You'd also have to replace basically all the electronics, as the stock stuff has all the "security" features mating them together.
There would also have to be a reworking of the suspension due to the extra weight up front.
Let's not forget about the trans.
Given all that, and the fact that you're talking about a car that was produced in pretty small numbers, and is out of production......I just don't see it happening.
It would be nice though!
