LPS are always a risk with any angel. My majestic ignores corals for the most part, although I suspect it played a role in ridding my tank of yellow polyps. He also seemed to like xenia and anthelia. I have no LPS.
Also, you should note that any angel could suddenly decide to take a liking to a coral after ignoring it for years. There simply are no guarantees.
If you decide to do this, I agree with Kahuna Tuna that you should try a small adult rather than a juvie. Mine was slightly less than 2" long when I got him, and already had full adult coloration. QT is especially important for this species, which tends to be very shy upon introduction. Getting it eating in a calm environment without distractions from other fish is a good idea (aside from the usual concerns about disease).
