You'd have to hold it there fora little while if you use 5 minute epoxy, then break off the dowel rod. It'll probably work best to put the epoxy onto the fuselage and just wipe a thin coat onto your backer piece so that you don't rub it off on the way in.
Have to agree, to get more wood on the backside, tack piece on a dowel any number of ways, apply epoxy and set it in place. Doesn't look that hard to get back there, its a straight shot to it.
