2nd the "remote possibilities" hint.

When recording choirs, I usually go for a spaced pair as main mic, and place it so it sounds great on its own. A well-set up spaced pair won't cause any hole in the middle trouble.
For a film score, a slight hole in the middle can work out nicely though, as music will less mess with dialogue. Therefore I could imagine spacing the mics a little too wide and using an additional center XY pair - start, maybe, with 120° between the mics. You don't want the music on the Center channel where it will just mess with Dialogue.
