That depends, you willing to get your hands dirty?
If the spar arrangement has to be changed, that's where you might have to get your hands dirty. I'll draw up the spars, and get the rest of the plane figured out if you'd be willing to do some CAD grunt work and punch lightening holes in all the spars. It's not a difficult or complex process, and I can walk you through it. It's just tedious. Expect about 6-7 hours of drawing circles and ellipses.
Unfortunately my 3-D cad skills have rusted completely through. I opened up Fusion 360 recently and literally couldn't even successfully import a 2D dxf file. So yeah, I'd be working on that thing for the next 6 months just trying to figure out the basic features. :'(
