I disagree completely, yes the drain is there for an emergency but honestly a trickle through the "emergency" drain isn't going to be the deal breaker... If you really want to do the math go for it.

Just because it has the word "emergency" people get their panties in a bunch. Especially for such a low flow and small tank. I would maybe think differently if I was setting up a 200+G as the flow is way higher. When I was researching the math and water movement in a 1'' bulk head herbie/durso style I believe it was that one single drain would drain approx 600/800gph depending on gravity and how long your herbie drain is in your overflow box. So if your are running a 1.5'' bulk head then that number would increase.

So if you're telling me you would be worried about 20-30GPH when your Single drain in a 1.5inch bulkhead which is common is going to affect your 800-1,200GPH your currently running through your single drain that is mind boggling.
