Sorry, you're considering selling a camera/lens combination that gives you a FF equivalent angle of view of 112-320 for a camera that gives you a 35mm angle of view?
Now, I completely understand the appeal of the RX1, and to be honest I could live with just a 35mm lens for the rest of my days, but the question is: could you? Will YOU miss the telephoto?
Also, the RX1 is $2800. A Sigma 35 f/1.4 (which outperforms the Canon 35L) is $899, and a 6D is $1789, so for ~$100 less, you get a FF DSLR and a fast (and very, very good) 35mm lens. This leaves open the option of adding other lenses in the future.
I personally don't like the DSLR form factor; while they're versatile, I find them far too big for general use (mirrorless cameras having come a LONG way), and if I'm going to get a large camera, I'd rather it be a medium format film camera.
You need to ask yourself whether it's FF/35mm + versatility you want, or whether it's a small camera you want.
