I'ii also say no for basically the same reason but I'll explain it differently.
To get your digital output you have to select the analog input for the turntable because your digital output comes from your selected input. You pass that output through your Rasperry pi and bring it back to a digital input on the 120 but in order to hear that digital input you have to select it. Once you select it you're no longer listening to the turntable so your digital output is no longer from the turntable. At worst you're going to end up with a feedback loop as the 120 passes digital input from the rasperry pi through its digital output to the pi which passes it back again.
There's simply no way of having the analog input from the turntable active to create digital output at the same time as you have a digital input from the pi active so you can listen to the corrected sound. You can only have one input active at a time and to do what you want to do you need to have 2 inputs active at the same time and have the amp doing different things with the signal from each of those inputs.
