Not sure if there needs to be any major changes to the incarnate system, and it probably wouldn't go over well since the horse is already out of the barn. What we could use is more content geared to challenge incarnates. I don't mean more trials, but maybe a neutral zone for incarnates only, with story arcs and door missions with higher difficulties. I can run door missions in PI with my incarnates at +4/8 solo with no problem. While it is fun considering the effort it takes to get you there, but we really do need more content for incarnates.
