My spur of the moment idea would have been to replace Smackdown with NXT completely.
NXT talent may not be ready, but it doesn't mean fans aren't ready to attach themselves to the NXT talent
My next idea is to have a couple of exclusive feuds and make the U.S title a centerpiece of the show
Give the NXT champion face time and make an effort to highlight international/ethnic diversity on SD.
If the U.S title is to switch hands, have it switch hands on Smackdown. Ideas welcome.
Simple; get the Wyatt Famiy on the show, have all the wrestler's gang up on them, and give the Wyatt's a shave and a haircut, then throw them into a tub and give them a bath. Ta Daaa.
