Just for the record, your post is rather misleading as I thought this was something that was actually happening.
That being said, I wonder if the transmission could even handle the torque. From what I gather, the ZF 9HP handles up to around 350-360 ft. lbs of torque, and a turbo V6 would likely put it in the upper 300s to maybe close to 400hp in that form. If nothing else, FCA would have to rework the transmission to handle the torque, or simply use a different one altogether.
I suppose FCA would experiment with a KL SRT8. A Trackhawk KL would be over 500hp easily I would think, but I'd be curious if the Pentastar would even reach those kinds of numbers. It would likely need to be direct injected, on top of the turbo-charging, and then with better internals, and other do-dads, and then maybe it'd be feasible.
