The simple way to do this is to lock the mirror with an electromagnet
once it has swung up and then release when complete. There was a range
of electromagnetic leaf shutters developed in the sixties that used a
completely mechanical action to fire the shutter, but an electromagnet
to vary the delay between opening and closing the shutter. The fastest
one I have is accurate to 1/250 sec with the top speed, 1/500, being
purely mechanical. You probably wouldn't even need a new timing
circuit, just a "turn this on when in burst mode" and a "don't
release mirror until shutter button released" subroutine.

There is a reason why K20D reduce the number of pixels recorded for

I'm certainly not looking for a big burst, just 2-3 frames.
But you know, I really don't know the tech magic anyway. I just kinda
suspect that if it was easy, all the cams would have had it already.
It's probably neither easy, nor outrageously difficult. It is very
likely deemed not worth the investment.
