What you propose seems to be not possible at all.



The Sony does not have that element in front of the camera!



What happens when you make the image circle (or rather: opening) smaller inside the lens (with the aperture)?

You get a bigger DOF.



What happens when you make the image circle in front of the lens smaller (think for instance too thick filters)?

You get heavy vignetting.



This should make clear to you that the placement is everything..
