Seems like reversing the tip rib flanges back to the rear spar (tip closeout aft of the spar permanently attached to 'glass) and stretch-forming an outward-facing offset mounting flange would allow a flush (no 'glass overlap) tip mount. Anyone go that direction to try to avoid the usual wave-like appearance of the overlap mounting approach? No real structural impacts beyond trimming the very end of the spar flanges back to flush with the now-inboard-facing rib flange, which would seem to have no impact given the continuous skin there and fore and aft brackets. Beyond that, just additional weight as far as I can see, which might be offset in the tip construction (CF and a Divinycel partial doubler just outboard the mounting flange for shape retention).
My build buddy already eliminated the double ribs inboard on his Patrol in favor of an inboard-facing stretch-formed flange, so fab and fitment is no issue. Re: that mod, Bob suggested stiffeners were needed on both sides of that single rib (or use a stiffer bulb-section angle, which was what Carlo did), but not an issue for the wing tip as far as I can see.
