Have you considered the Canon M5? I don't own it, but you can get body only for under $1k, and with a kit lens for a few hundred more. Besides, it should work with your current lenses.
The ef-s lenses won't work on M-body. They work fine on canon crop sensors, but you'll get vignetting on canon full-frame camera bodies. For light-weight photography, I have a canon sx50. 12mega-pixels, but that's good for all but the most extreme telephoto shots. Good Luck---
