Design Choice

Still contemplating a design for my teardrop. I've got the BenRoy Plans however, my trailer is 5 x 10 and I'm wondering if there's a design for a 5 x 10 that will make it look as balanced as a 4 x 8.
Also think the trailer will be taller than 48" so I'm going to have to join plywood sheets together. I plan to make the plywood extend down to cover the frame.
