SY-1000 GK3 and QC setup

I want to use sy-1000 with QC. I have pickup GK3 installed on guitar.
Routing is… GK3 pickup to SY1000, jack from guitar to QC. Audio from SY1000 to return1/2 block in QC. I put this block depending if I want use QC power for sound design or just strictly with no processing. Since sy1000 has its own output from guitar I don’t need to use sends from QC.
Is it good way to connect this two units?
Is it ok to run stereo returns in single row
Give me some feedback with it… Thank You.
