I first thought about multiple because of the close assault fields of fire. But the as your close assult need to be done three times, the cupolas will be too expensive in satchel charges etc. to crack. Also a big issue is that AI has three times the shots for a single simulated cupola.

Making it a 360 turret and using blocking terrain to give it a real field of view is more realistic. Also you can imagine that in a close assault scenario the cupola defenders might be a bit more combat worthy than waiting for certain death because they can´t fire back at the flanking enemy.
