I'd NOT alter the shape of the canopy. Take the time to add extra ripstop to the rib and sew it back together properly, even if that means picking
out the seam and re-sewing in the rib.
If all you have is ripstop tape, try 2 layers stuck to each side of the rib, with some overlap that you can trim to shape and sew back in. If the
tape runs back into the rib, the adhesive should be strong enough, or you could sew it to the rib face as well.
