It's always bothered me that the only pheasants found in Skyrim were dead ones.
Would it be possible for me to change all the chickens ( Or at least make a duplicate of a Chicken ) model's into a Pheasants? With just a switcheroo via creation kit? Or would I need other programs?

I think it would be cool to hunt Pheasants along with the other wild animals in the game as sport.
I'd like to make it a mod, I've tried searching and it seems it hasn't been done before.

So would this be possbile, via Creation Kit?
If not, what do I need?
