Qu-Pac and serial connected Audio Rack

Hello guys, I’m planning to get a new Qu environmentbfor my new studio, and I want to have a Qu-Pac connected with an AR168 and an AR2412 serially. Is that possible when the Qu-Pac is only able to expand to a 38-input mixer?

Yes it is, for my production system using a QU Pac i do it with a AR168 and AR2412.
I normally will put the AR2412 first in the series, not that it really matters though.
