Live Rig Configuration

Hi all, after an exchange with tech. support in order to configure my Quad Cortex for live as follows:

Quad as effects pedal connected in 4 cables with my amp on stage which will serve as feedback and good feeling (acoustic pressure, feedback, etc…) and in parallel simultaneously, send my amp sound without cab but with IR on FOH.
Here’s a photo of what I’ve managed to do, it seems to work, can you confirm if there’s a mistake or if other methods exist ?

I also have 2 questions:

1 - Is it possible in this approach to replace the sound of my amp + IR in FOH by a simulation of amp + IR but keeping on stage my real amp sound with the method 4 cables (I have already made this configuration with my Helix at the time) and if yes of course how to achieve it?

2- Is it normal to lose the stereo effect of an ST delay when using the doubler (if so, what a shame!)?

Thanks in advance, and don’t hesitate to put up some screen shots of the QC, it helps a lot with explanations :)!
