It would be fairly simple. Along the side of the crank, install something that telescopes to the ground. Something like how a crutch or ski pole extends.

On the non drive side, somewhere near the seat-tube, a simple device to lock that crank into place. This could probably be attached to the water bottle cage bolts, so nothing would need clamped to the frame.

The type of nicer bikes that you normally wouldn’t want a kickstand wouldn’t want a weird crank either. So the market is for bikes that already have kickstands.

So yeah, it would probably work. There’s no market for it though.
