Anything custom can be done. What year engine do you want to put in? I've enjoyed seeing guys cut up and rotate the power train in W-body's to run 3800 or LS engines in RED configuration. Much more work that I currently have time and space for, but it's impressive every time.
If you're just kicking tires on the idea, be prepared for many reasons you probably don't want to continue considering this oddball type of conversion.
