Splices are ordinarily located where yours was to keep the weight down, and to allow for further shaving via a tapered top.
Fair leads,

Hi Brion,
Thanks so much for your opinion... The factory internal splice extrusion I have is 64", and weighs about 20 lb, so it definitely isn't insignificant at that height. I have a little leeway with the splice location. I could make it a few feet lower, but not higher... As seen now, the internal section could overlap the top spreader bar location by say 6 inches with the splice 28-30" below the spreader... I'm thinking that moving it closer to the center of the unsupported span is a better move...
So now that you see a basic rig diagram, if I get you the RM data, what's a ballpark cost to have you guys run the rig calcs to be sure all is well???
Thanks again for everything!
