Now let's talk XE3 ... and we'll soon push you along to an XT2, then 3 ...

Kidding ofc, the X-E2 is a fine camera, you will appreciate the extra AF speed and better LCD
If you're talking AF adapters, there's a few out there, the better ones being the Viltrox EF-FX which is reasonably priced [I had the version for M43 and it worked good enough] - or the fringer pro FX - a much pricier option but I'm using one and it works almost flawlessly. You get the odd bit of hunting, but I've only tested cheaper Canon lenses. I imagine higher end L glass will work even better. This adapter has had numerous updates and each time they have added more and more lenses, including third party [Tamron/Sigma etc] one of the reasons I got it to begin with is the lack of third party support for Fuji - no Sigma or Tamron or Tokina - with this I always have the option to use more budget friendly Canon mount lenses whenever I please.
If you only need MF adapters they are a dime a dozen, well, more like a tenner a pop, they're all much the same - just spacers to fill the flange distance void between Fuji and Canon EF mounts
