Actual fantasy football

I've got this idea, but I'm not sure how to implement it.

The Premise: Actual Fantasy Football. With orcs and elves and dwarves, etc.

The Idea: I want to re-skin American Football to be Actual Fantasy Football. Have a website that automatically takes a feed from somewhere (I haven't figured this part out yet) and convert it to fantasy names and fantasy races.

Then, people would sign into the site and make their own teams, just like regular fantasy football.

Then, I want the site to programatically convert game statistics into battles. Change touchdowns into something else. Conversions. Interceptions. Yardage. Passes. The whole thing.

I haven't found anything like this online. If you have, point it my way. And if you have some ideas for how to accomplish this, I'd love to hear them!
