Even if the depth is enough for focus and aperture motors, what about the width? The adapter is going to be very ungainly. I could see a protrusion on the bottom but I wonder if it would be enough, because you wouldn't want it going past the bottom of the camera.

Edit: somebody pointed out Sony's LA-EA4 adapter which does exactly what I describe, so obviously it's possible. Definitely ungainly though, and expensive for what it is.

This suggests that it 159 grams:

The Pentax DA 1.4x Rear Converter is 126 grams. I barely notice that I'm carrying that.

My K-1ii weighs 1010 grams without battery grip or lens. What would a Pentax new-mount mirrorless camera weigh?

(A Nikon Z 7 body weighs 675 grams. 335 grams lighter than my K-1ii).

I don't think it is expensive for what it does. It would be a one-off purchase. And I suspect that it would cheaper as part of a bundle/kit with a camera back. That appears to be what is happening with the new Nikons and Canons.
