The project is quite doable.
Using a micro or adding an ADC should allow a volt meter to be built round a Pi but I'm not so sure about achieving 16-bit plus sign resolution. Not sure that's even needed.
I would suggest that if the project is to have an OLED display it might be better to step it up from being just a volt meter to having some beginner level oscilloscope capabilities. That could make it a more appealing and useful project for beginners to undertake.
But it's not clear what "beginners" we are talking about here.
