Coming back to this thread for updates!
Finally went back to the studio and managed to test things out.
My setup: Logic in multitrack into Mixbus 32C V4 in multitracks via Jack.
I have on every track and bus in 32C a version of Britson and a version of Satson connected in groups as usual so i can control in groups from the bus instances.
BUT britson and satson are before the native EQ and Comp from mixbus, you can drag them on top on every channel and bus.
One word: MAGICAL!

Satson is more fat and round while britson gives more mid and high presence, so the combination is lethal. 99% of the times I have the FAT button always on!
So yeah this setup for me works great, don't really need anything else as most of compression has been done beforehand and the eq is done in mixbus.
Then the last thing to do which i prefer to do in logic at the end, is to bounce the stereo track and do a final premaster with logic.
Cheers
