I was thinking that I could get a cheapo Scattante from performance. I would have a machine shop/welder do the drilling and welding. The DT on those are aero profile so no dice on the clamp on. I was thinking that since it is aero that a mitered tube may work, but I think the idea of drilling through and welding the tube is a better gig.

If you look at the zoom view you see the stops. I would put the hole just right of the middle stroke of the "E". On second look the aero tube would be too wide for a miter cut.
