Stickaflex or laminate in with grp where two ideas I had in mind.

I took 30 x 5mm flatbars the length to fit inside the wing and drilled 2 holes through it to the outside diameter size of 8mm nuts. Knocked the nuts flush into the holes and brazed (weld) fast and grind off the excess of nut protruding out of the plate. Drilled similar spaced holes into the wing brackets at correct alignment.
A couple of random "locking" holes were drilled through these plates for the GRP to grip properly to plates and prevent movement when laminate is filled into these holes.
These "bracket" plates were bedded on epoxy and laminated to the bottom of the cycle wings. The bolts were cut to length not to touch the wings when fastened and installed with a bit of Locktite fluid applied.
Need and clean installation with no bolts through wings..

EDIT: I laminated all my wings, fenders and bonnet using CoreMat sandwich construction. Used 3mm CoreMat between two single layers of 450g/csm and is immensely strong and light and stones from road have no impact on the wings/rear fenders because of the CoreMat which protect the top layer.
