you know carcrazy, A lot of people told me putting a V8 in my R170 was "not possible" or to just get something that was already fast. But I was in the same boat as you - the car had a lot of sentimental value.
You can overcome any challenge if you put your mind to it, and don't be afraid if you feel like you are "ruining" the car, because in the end it will be amazing. I "ruined" my perfectly good SLK230 to put the V8 in it, but now it's a damn incredible car!
Finding a supercharger for the V6 will be the most challenging part. Kleeman supercharger kits are well over 8 grand, so you're cheapest bet is to find a used one on craigslist for a 32. there are other options too such as a centrifugal supercharger which could be adapted, or even a custom one made into the intake manifold like the SLK32.
