Take the guts out of a Panasonic S5. Put them in one of your insanely beautiful, minimalist bodies that are carved out of aluminum, platinum and white gold alloy. Upgrade the glass stack over the sensor so you have something that works well with wide angle M glass as well as all L mount lenses. Add in your processor level camera science. Make the EVF gorgeous. Keep the size difference between this camera and the SL models in the same relation as Panasonic does vis-a-vis the S1 and the S5. Drop it into the market for $4,000.
If I could add one more thing to the list: make a 50mm f2.8 lens that's just perfect. In chrome or black. Nothing too fancy. Just, you know, perfect. And put a price tag of $1,800 on it.
The combo? Heaven.
