Good idea, Larry, I will take some before / after pictures for reference
I changed my plan a bit, The lens has a protection tube that shifts over
sun-head when the lens is in the camera bag.
I will copy the sunhead on this tube, this becomes now a detachable
sunhead for APS-C use.
The original fixed head I will cut away comepletely

Could you maybe post some pictures showing the vignetting? Maybe of a
grid so that you can quantify the difference you make comparing with
in progress photos?
Do you maybe want to try trimming one corner of the petal hood so you
can compare with the original and see if it is making a difference in
that one corner? Perhaps the lower left because that one is likely to
be down no matter whether you are holding the camera and landscape or
portrait mode?

You're right: the hood is permanently attached. Your suggestion to
remove it completely will be my back-up solution if my cutting fails.
The front lens is extremely ball shaped, that makes it vulnerable in
practical use.
My step one will be to cut away from the hood just keeping enough to
avoid the lens toughing the table if I put the lens on the table with
front lens down.
If in that stage I can reach FF coverage down to 12 mm, I am satisfied
for the time being.
