Analog 4 to Octatrack and back again

Hi
I’ve got an Octatrack and an Analog 4 and wanted to a) record direct to Overbridge and b) have a master volume knob.
I’ve come up with the following routing and wondered if there are any disadvantages I haven’t spotted. It may be a bit convoluted but seems to work.
Thanks

Analog 4 to Octatrack - connect 4 individual track outputs to Octatrack ABCD. Switch off tracks to main and to FX in the Voice Routing page (section 9.5.2 in the manual).
Then connect the output from the Octatrack to the Analog 4 inputs and turn up the volume in the FX track external in.
Then the Analog 4 main out goes to speakers or you can record direct to Overbridge. The individual track outputs from the Analog 4 don’t have the Analog 4 FX but this may not be a major problem as the Octatrack can add effects.
