On the off chance that anyone is actually interested, I'm happy to say that this worked really well.
I hit the fermentor with about 3 psi before cold crashing, and when I checked on it the next day, it was still holding pressure.
The closed loop transfer also went very smoothly.

This thing is so much easier to clean than a 10 gallon corny keg. I might buy a second one.
