I'd say go for the X-E2 its a much faster camera than the Pro, and you can get a hand grip to bulk it out a bit for you. If you are used to a DSLR the optical finder of the X-pro will still take some getting used to as it's a rangefinder so your still not viewing through the lens.
The EVF is great to use and being able to see your exposure before you shoot will be a feature you will soon enjoy,
Hope that helps
