I've done exactly that: I was at ~100wpm with "advanced hunt and peck", and decided to learn touch-typing in Dvorak to "do it properly".
I type a little slower now, and my hands feel pretty much the same, but it makes my computer that much harder for other people to use so I'm calling it a win.
It's actually pretty fascinating, though— I can still type blind with speed in either layout, but the process is completely different. I know the location of an arbitrary key in QWERTY, but I'm not sure I could actually give you the Dvorak layout without putting my hands together. I don't use Dvorak keycaps, which might have something to do with it— on one of my laptops I actually rearranged the keys to be accurate to neither. I don't like it when other people use my computers, and I like that experience to be mutual :)
