If you can manage to build a small cross sectional area and still get the necessary stiffness, it seems like it would be less susceptible to being blown around by wind than one with a taller wider fuselage. At least I get that impression from my profiles, like the Ukey, which resembles a primitive TEOSAWKI with a foam wing and a much smaller stab. Its fuse is actually just a 1/2" wide pine(yes pine) board, barely tall enough to cut a hole for the wing to pass through.

EDIT: Correction, I don't think the wing actually passes through it, just the joining dowels. That's what makes it so indestructible.
