Your weathering looks great, I think it really makes the model.
Is it too late to offer you some free shipping stencils for the hull sides?
I'm just finishing a similar project and I've got a bunch of Archer rub-on stuff left over.
I think your build is fine as-is and I certainly understand the concept of "when its done, its done" (I, on the other hand, never seem to really finish anything) but if you wanted to add a little something extra....
