The energy you give to the string is hundreds of times more than the energy you give to the kbd (do not consider this as an exaggeration because I'm a bass player). Also lateral stretching of your pointer finger is something easy to train, I used to have that experience while learning a piano playing.
I don't understand why do anybody invent a new kbd layout after Dvorak's work? He gifted us a beautiful set of aoeui layouts. Just get used to it and help with this information to your friends who are willing to get rid of Qwerty, that's it.
