rpc07, since you're already caring for hard / stony corals (lps), you should already be monitoring your alk, ca and mag. M. digitata water requirements are similar. That location would also be one of the brighter locations in your tank par wise, which would be appropriate.
Plus if it does well, you could try other form factors that Montipora exist in - encrusting and plating.
I agree with Nick92515's statements.
