You really didn't get it yet? 
There already are cameras with OVF + EVF, like the Fuji-Pro or some Sony α types. But to "turn down the lights" in an OVF putting as advantage...? The only real advantage is: an OVF needs no battery. But the rest of the camera does, so I still see no advantage or excuse for a manufacturer to put two different systems in the same space - LiveView is already standard in nearly all DSLRs.
Except of course, a Leica type which doesn't even have a LCD screen... meaning, no histogram, no accurate focus.
Also I don't understand what you want with an f/1.0? Find out, what a wild guess a DSLR AF does with it? Want to reduce the keeper rate? No offense meant, but your theoretical ideas have only theoretical use. Mind games...
