Not really sure why you would want to mess around too much with our long term no.3 (a position we've really struggled to find someone for since Ponting). Marnus has been brilliant there. Laboosh and Smudge coming it at 3 & 4 is also a lot more intimidating to fielding sides and offers more resistance to a batting collapse when the fielding side have their tails up with an early wicket.
To me, there's a lot less shuffling and potential for unsettling a line-up long term by Uzzie simply moving to open in place of Harris and Head slotting back at no.5. Khawaja should open alongside Warner for the next 12 months as we need that experience up the top for the tough oversees tours coming up. After then, we can evaluate the likes of Puc, Street, Hunt etc. to whoever is knocking the door down with weight of runs over a few shield seasons.
