It's been four years with this look now so an upgrade is never a bad idea.
A way to differentiate the looks of Dynamite and Rampage would be ideal but hard to do when taping both the same night. Because they've already seen at least two killer matches by that point, the crowd is often already tired by the time they start taping Rampage. To take an extra 30 or so mins to change the set a bit would kill them all together.
