My thought from experience is that your design may be OK, it is the construction of which is doubtfull. How do you plan to hold all the parts in perfect alignment while the spruce spar gets glued into place?

You can build in two halves, however once each half of the fuselage is let loose from the board, they spring straight. Then, how do you join the two halves, and ensure the alignment is going to be true before gluing on the side panels?

See what you are getting into?

That is why so many older designs work with the tried and true box frame fuselage. You just build two frame halves, then join them together. Bit by bit adding one more brace or cross brace, keeping in good alignment. Then, when finished, bend in the sides to a taper in the stern. You have to consider what may happen after you lift the half off of the flat board. As the A/C got rounder, they simply added on semi-circular bits to the correct appearnaces before adding the skin. Will it stay in perfect alignment or not?

Brian Taylor likes to build a central H shaped box laid down. The center pan of the H is for mounting servos and abtteries. He then adds sides, bending them to a point at the stern.

You need to take a look for a few more examples of the construction method you are envisioning. See how they did it, and then adapt your intents. There are a Kaboodle of plans out there showing different methods of fuselage construction, one of which may come close to what you are representing.
