why not just get a mirrorless camera if a single lens is good enough for you? one of the main advantage of DSLR is the large selection of lenses. I'd prefer carry a X100 than lugging a DSLR around! you should also look into the D800 since you don't have much invested in Canon glass. Sony sensors are miles ahead of Canon.
I second the X100. If you aren't going to change lenses, why even bother with a DSLR?
