113% Slumbercoach?

I'm on a search for the perfect woody profile. Comments and opinions on my latest scheme welcome:
Enlarging the Slumbercoach profile by 113% maintains it's lovely proportions, and yields a body 10' long by 54" high. Plan is for 5' width. The curves on the bottom of the profile are maintained by using a 6" skirt, that will also cover the trailer frame. The non-functional decorative 6" skirt at the bottom is made up for by adding that 6" back in at the top with an extra strip of plywood. Plywood seam covered by a piece of woody trim.See photo below, the dashed lines indicate where plywood skin joints occur. Cabin space ends up with about 45" headroom.
Am I missing anything obvious here, aand does tis make any sense at all?
Thanks, Joe
