Using the tele alone makes an OK contact print but enlarging from a normal lens is much sharper
so how about go the other way
Turn the not too well corrected Adon into something more like the Bergheim in feel
Very long focus and while keeping it's relative "sharpness" intact adding to the aberrations already present or making better use of them for portraiture

How about an ImaDon?

No, no
not a good name at all


An imagon aperture disk

Softness and yet able to focus on GG without a chemical focus issue as in the bergheim
Focus shift, yes

that's as far as I've gone. Thought it would be a fun exercise
I used the imagon disk as a waterhouse stop
maybe try in front of front element
