Has anyone mounted SPS corals to glass walls?

Looking to add more corals but running out of real estate on the rocks, so I thought about gluing the plug right to the glass. Anyone done this and have photos? Also, what would be the best way to glue them and still leave the tank able to be cleaned out later if it torn down?

Mount it to a magnet and attach to the glass with a magnet on the outside, a la Tunze power head style :idea:

I think something like this could work

They're available fairly large, with an opening of like 3.5 inches or so.
