Well, the box lid says 1580 mm span and it looks like a swept L/E straight T/E job so the DB wing could be made to fit ok. It looks as though the Skymaster section might be a bit thinner, but I doubt it will make any difference. So yes, the idea is good, two dowels at the front and a bolt at the back of the wing, looks like torque rods for the ailerons, but you could put a couple of mini servos in the wing, either fixed U/C or retracts, depending on wot you got, and just fill in the outlines for rudder and elevator. Keep it simple, use hard 1/4 squ balsa for your rudder/ele pushrods and you will have zero trim/temp changes. So far as wing/stab/thrustline, well you can go 'zero/zero' or, like Yoshioka and Matt (Blue Angel and Atlas) 3/4 degree positive in the wing. Either will do and it will be difficult to tell the difference.
Good luck, and lets have a pretty colour scheme on the thing, best you supply a finished photo or two.
