As others have mentioned, I think the interesting thing here would be understanding the latency for processing the signal. Anything in the single digit milliseconds would be fantastic! I know at one point I was looking into Raspberry Pi and ended up on Pedal Pi[0], though I couldn't get the parts I needed to make it work. I ended up using Teensy[1] and related audio shields[2] to get things working from a sound/acceptable delay perspective. But being able to get things going on a Pi would probably make more of the advanced input controls much simpler to implement simply from a OS support perspective (like in this project with the WebUI). The UI I'm seeing in this project looks great and it would be cool to potentially see something like kits/preinstalled images roll out for this!
