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

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.

Thank you Donald - much

But I actually stuck that on the top of ALL KRnet messages, but forgot to

I can see where this would be needed in what I would assume would be the
working part of the wing ( mostly outside the WAFs ). But not inside the
fuse
