Simpler way to what?
Put you wing into your full fuselage airplane. On my last few full fuselage airplanes I have been able to insert the wing into the fuselage without cutting out the entire bottom. My technique was to cut a triangle shaped notch into the top inboard side of the fuselage (to clear the pushrod/horn) and slots into the fuselage side to allow the horn arms to slide through. Then just slide the wing in (before you add the flaps) glue the slots and triangle back into place, align the wing then glue it into place. Try it, you may like it!

Jim, there is an even easier way, cut a slot about 1/2 in by 1/8 in at the trailing edge of the wing, cut a slot in line with the push rod ,without the clevis or balljoint,push the pushrod forward to shorten the slot.
This slot will be about 3/16 in by 1 1/2 in long.
Put the horn in the wing slot and slide it back to the rear of the slot at the trailing edge,then slide the wing into the fuse,align and glue.
The horn and its parts can now be slid forward and inserted into the rear of the wing and reinforced with a fiberglass wrap.
The fillets will cover the slots at the trailing edge and you only have the patch the slot for the push rod.

Yup been doing that for 30 years now :-)

Build the fuselage in two sections, a front section which slips over the wing from the front, and a rear section which slips over from the rear. If you think about it, the structure and function of the front and rear of the fuselage are rather different and no reason to make the whole fuselage in one piece.

That appears to be the thought process of Tom Morris as well.
Building it in two parts also makes it easy to do as free flight style , i/16 in sides with a warren truss of 1/8in sq glued to the sides and perimeter,jig it up and connect the sides with 1./8in sq also in a warren truss.EXTREMELY STIFF and no banana shape. No formers to dodge with the push rods.

The main reason to make and keep the fuse in 1 piece is for alignment. When you make a 2 piece fuse it can get glued together at an off angle. and many times does.
It is just much more bullet proof to keep it 1 piece.
Todays laser cutting would help a lot but you still have a better chance to get one half off a little
