When I moved to France I would use the Canadian French keyboard layout which was QWERTY-based with subtle changes and a whole bunch of modifiers for different accents above/below standard Roman letters. I was surprised at how quickly I adapted, even to the character variations. It took only a week or so to become proficient. While dvorak et al are certainly more different, I think it isn’t unrealistic to master those layouts in a week or two. Muscle memory is a remarkable thing.
