Yep, the Bean Animal is what I setup on this tank. 3 x 1.5" drains, with 1 x 1.5" return. 1 drain in full siphon with a gate valve choking it, another drain with barely a trickle, and the third is 1/2" higher than water line at the top, and 2" above water line in the sump completely dry. So technically I have a Herbie (2 drains with water), but my herbie-emergency has the bean-animal extra siphon tube on the top which turns it into a 2nd full-siphon even before the 3rd drain even gets wet!!
Sounds like you have a good test plan. I did many power outage tests on my tank while in the first couple months of tinkering, needless to say I changed a few things after each test, and a couple tests I had to abort before I needed rubber boots
