Secondly I could turn my 1 1/2" drain into a "Herbie" with a gate valve and use one of the return holes for the emergency drain, leaving me with one hole for returns. The tank currently has 1 - 2 3/4" hole for 1 1/2" drain and 2 - 1 3/4" holes for 1" returns.
I'm not sure I understand why one needs an emergency drain for the Herbie style, but not for the Durso.
Oh my, sometimes I wonder why I started this? (Just silently venting)

The Durso should be running "wide open" with no obstructions. The Herbie is deliberately obstructed by a gate valve, which can get clogged pretty easily by debris, or an errant fish or snail. If your drain line gets obstructed, but your pump keeps pumping, your floor gets salt-watered. The second drain on the Herbie is to provide an automatic by-pass of the primary drain in that situation, which will take over the flow if the water level gets high enough in your overflow.
Your thought for using the smaller hole for the second drain is feasible only if it can handle the entire flow from the primary when it is turned off.
Good luck! This can get complicated, but you'll get there.
