Pick which one you feel comfortable with, learn how it works first before you mess with it.

Doing this through one bulkhead would be a bad idea. The reason for the redundancy is to avoid potential disaster. For example, my BeanAnimal overflow saved my a$$ the other day: I had several nassarius snails apparently climb into my overflow and die in the main siphon pipe. If I had one bulkhead and they managed to get lodged in the pipe somewhere at a point either just before the bulkhead (presumably where the network of siphons and emergency drains converge to enter a single bulkhead in your proposed one-bulkhead suggestion) or in the pipe on the other side of the bulkhead the redundancy of the extra overflows would have been moot and I would have had a wet floor.
