Hi Scott!
I suppose this technique would work, but your glass would be
"flat" and you want to bond it to a curved surface. I suppose if
you bonded it to the wing before it completely cured, say within 1
day, it would be flexible enough to conform to the shape OK.
You will still have the task of feathering in the edges to make
a smooth seam.
The other factor is that the foam bond to the glass does provide some
additional stiffness, but since it's not a sandwich, I don't think it's
providing that much additional support.
If dealing with a foam plug is an issue... I suggest using toothpicks
and a hot glue gun to plug the hole, then start sanding. But I would
probably feather the edges of the hole prior to plugging with foam.
