I believe they will be fine with the spread aspect of it all. I'd be careful as to intensity because these lights have severe hot spots because of the lenses they use. I have a viper spectra black box over my 37g display and I just upgraded (ordered) to a pair of ai prime 16hd's. The spectrum coverage on the mars boxes leaves something to be desired as well. According to brs, the viparspectra boxes have the best spectrum coverage. But they all work just about the same. Just something to consider! Especially knowing your ai's are probably providing perfect par distribution and spectrum coverage. Food for thought. Move the corals who need the least care, are the most hardy, and you would stand the least to lose. See how they adapt, then consider moving the others.
Ps: when you move the ai's to your 210, use a pair of the black boxes on your 40 if you plan to keep it assembled. They are not the best lights, but they will 100% for certain grow corals!
