Perhaps take and paint the explosed bare metal after you drill the holes with
epoxy paint
How do you drill holes with epoxy paint? :)

Looking at a simple vertical shear moment diagram for a wing fuselage
arrangement like the KR(treating the spar as a beam) with a
questionable
but perhaps not unrealistic assumption that the vertical load on the two
longerons is equal (this assumes the weight of the plane is centered
within
the fus
Stephen this is exactly how the stress and load factors are determined in
the Marcel Jurca replica fighter designs. That being said however this
designs have a one piece wing which is fastened to the fuselage the same as
the Pazmany designs. This would be an easy enough change to make on the KR

The shear load is not affected. It is always the total weight that is
being carried by the spar. Increasing the spacing between the spar caps
does not affect the shear.

Thank you for that, advice on this level is very much appreciated.

This is not correct. The neutral axis is very near the center of the
spar
and it is the best place to put holes.
A reinforcing ring is an excellent idea. You should feather the
edge ... prevent creating what is called a stress riser.
