Herbie Drain

[jc03]

Hello,
I'm trying to minimize CO2 loss and would like to move from the Durso standpipe to a Herbie setup. My problem is I have 2 built in overflow boxes that only have a single 1" bulkhead a piece. Whoever manufactured the tank separated each overflow with a baffle that severely limits the space to put any other bulkhead. My only thought around this would be this: Can I use the left overflow box, with the 1" bulkhead as the full siphon and use the other overflow box on the other side of the tank as the emergency drain? Thanks in advance.

Here's a picture. I'd appreciate any insight you may have. Doing the siphon in the left box in the left overflow box and the emergency in the right seems like it would work but I'd just like to hear from someone who has experience in it before I start cutting pvc. Thanks.
