I honestly have no idea what you're arguing against here then? Open mechanical shutter and get the sensor ready, then when the shutter is pressed, raise mirror, trip electronic shutter, done.
No you can't see through the optical viewfinder when the mirror is raised when the picture is being taken. There's going to be mirror black out with an electronic or mechanical shutter.
Yes, you'd lose some of the advantages of the electronic shutter, the floppy mirror will rattle around causing vibrations and noise, but having the option to access 1/24,000s shutter speed and still use the optical viewfinder would be handy for shooting wide open in bright, sunny conditions.

That answers that! Good find:)

afaik, the K-1 disables triggering the flash whenever the electronic shutter is enabled and it looks like the kp does the same (from page 52 of its manual). My understanding is the electronic shutter on current cmos sensors are pretty slow rolling shutters that don't sync well with flashes resulting in uneven exposures or major black areas depending on the specific equipment/settings.
Here's a good rolling shutter example from the k-1: Does the electronic shutter provide anything other than ultrafast shutter speeds? - PentaxForums.com
I also don't see why electronic shutter with the optical viewfinder would necessarily be disabled, but definitely someone should check:)
