Sure, but that will require users to get used to a different layout. Dvorak (http://en.wikipedia.org/wiki/Dvorak_Simplified_Keyboard) does this. It isn't very popular though, as it's few people want to spend time relearning how to touch type.
How is that? Somebody who doesn't know how to touch type is usually having a pretty hard time locating the keys on a QWERTY keyboard. Tactile typing (I just made that name up) doesn't require exact knowledge of the key placement as you need it when touch typing, but you still need some kind of muscle memory if you want to achieve a reasonable speed.
