I am not sure using a semi transparent mirror to use sensor AF would function without problems... Putting a piece of relative thick glass 45° in the light beam results in a slightly different projection compared with the mirror slapped up. So how more precise will that be than the conventional calibrated methodology with a second mirror and AF sensors.

Fortunately, I don't have to solve whatever technical problems implied by this solution

In your suggested solution the sensor collects far less light than a pure MILC collects what will be a disadvantage also for AF sensitivity.

The SLR's AF already collects "far less light". I don't think it's impossible to reach -4EV in the future (matching the K-3iii... except the K-3iii reaches -4EV only in the center).

Most light will be transported to the optical viewfinder, if not, the advantage of the "bright" viewfinder in the K3iii disappears.

Nope, the optical viewfinder already collects "far less light". There might be no difference between a standard SLR, or there might even be a positive difference - given the removal of the metering system (less light loss in the pentaprism?).

And let's turn it around. In case no DSLR's existed but just MILC, should it be realistic to assume a camera brand would developed a DSLR to solve problems of a MILC? I don't think so...

There's nothing to turn around. This is just a possible evolution for the DSLR.
