Couldn't the hand positioning be mostly solved by remapping the few keys that pain you the most ? For me it was the control key and escape keys, and the others keys are otherwise standard. Also I'd argue people suffering from RSI shouldn't be striving for speed or efficiency that much. Some people switch their mouse hand or reverse buttons basically to detune, or split the load to other parts of their body, speed/efficiency be damned.
