Well anything IS possible and it is an intriguing idea, but I don't see anything like that ever happening. If gas hits $5-6 a gallon and stays that way (which could happen) and the V8 sales take a major dump as a result... MAYBE I could see Dodge investing in that kind of money and technology for a V6. But the Hemi V8 is clearly the star of the show in the Challenger and, barring a bizarre unforseen economic circumstance, is very likely to stay that way.
