Should be possible. Check my thread on V8 conversion as you will have similar issues. Mechanically it is not that hard. The biggest problem I am facing is making the electronics happy. I am about to do the swap and I have a plan that at least in therory should work. I considered the SRT6 engine but felt it wasn't a great investment since you can get SRT6's pretty resonable and they would always be worth more than a conversion. So I decided on a V8. I am not too far from Oklahoma in the Dallas area if you are interested in learning more first hand.
