I doubt it. I don't think people that can't be bothered to learn to touch-type are the ones going out and learning an esoteric keyboard layout.

When I made the switch, I was reliably about 95 WPM (touch type) in QWERTY and topped out at around 105-110 in Colemak.

I use dvorak but I'm not sure I really "touch type", I can type without looking, but I don't really do the home row thing and I potentially don't even use the right(correct) hand for some keys.
