i.e.
- holding space and 'V' should result in an an 'N'
- holding space and 'C' should result in an 'M'
That way for two handed touch typists the learning curve is easy because you just do the same movement with a different hand.
This is how XKCD's Mirrorboard does it:

Considerations:
- This does mean '?' and '/' would need to be mapped to somewhere else - not sure where Mirrorboard puts them.
- Capital 'N' is still a pain in the hand until sticky keys are implemented
