Yes, TS!!
Reminds me of the story of Brett helping Bob put his Crossfire together.
This looks a lot more difficult, but you have less need to improvise. The deal at the NATs could have *easily* been done at the field and flown 10 minutes later.
BTW, after having done *many* repairs kind of like this, might I suggest making a bunch of 1/16" balsa "diamonds", maybe 1/2" wide and 2.0 - 2 1/2" long, with the grain running the long way, and then cut through the sheeting to inset them into the wing across the joint. Cut around each diamond with your knife, pull up the sheeting, then glue the diamond into the foam with epoxy. This will create a bunch of low-angle splices to tie the two halves together. Let it set, sand it all off smooth, then refinish. Essentially every airplane I have has similar repairs, either from damage from handling/thermals, or stress failures.
