Mongocanfly's suggestion had the most appeal.
I tacked some SS 8-32 machine screws to some thin stainless sheet from the scrap bin and gave the back side some 'tugboat antiskid' for the glue to interface with, cleaned up the recess in the emblem
glued it in

@Joedoe: fursure mon ami. I finished my poutine, got off the chesterfield, grabbed me tuque n mitts, stuff the sugaring gear in the ol trapper nelson and went out to d sugar bush on the ski-doo, but does trees she all froze up and syrup she not flow! what a kerfluffle. I did not want to wait for breakup or hope for a chinook so I had to use the syncrowave instead. Sadly those were not robertson head screws either. eh
