If it looks happy it probably is! Good luck! Have you tried moving your flow around to help the cyano problem? deadspots are like a cyano breeding ground lol.
if you're leveled out and feel confident in the stability of the tank then go for it...GO SLOW.
What i would caution against (I've seen a lot of people do this, and done it myself) is getting "easy" corals like leathers and other stuff just because they have the "itch." You end up with a lot...
