Super Freak
It would not be a bad choice. First of all, Freddy is one of the highest selling modern horror icons. That is why the licence is so valuable. Second, they made a lot of Jason Voorhees sideshows which all sell for a great price on eBay, and the Freddy Krueger ones sell at a high prices as well, especially the normal burnt ones like the Classic Freddy and the Dream Warriors Freddy. If people bought all these Different versions of Jason, why wouldn't the Freddys sell as well. I could understand you saying that there is little difference between most of Freddy attire in the films, which is true. Sideshow does a great job of capturing the difference between the makeup looks of Freddy (good example, the classic Freddy and The Dream Warriors Freddy)
It would be a poor business choice. The ones Sideshow has made pretty much cover the significant changes to the character over the course of the movies. It was stated in chat that to turn a profit on Gandalf they had to sell 3000 pieces. I'm not sure if that applies to Freddy as well, but I just can't see them selling that many of each Freddy, especially at the price they'd need to charge to break even let alone turn a profit. As cool as Jason was, and as different, there were versions of him that actually sat on their website for quite a while and really only sold out as the average price for other figures increased to about $75 making the $49 ones more appealing.
Now that said, I'd love to see what they could do with the license now, given that the figures they're making are simply awesome.
