If it's all put in a case with extension lead connectors from the Pi to the case; it will be possible to add a blocking diode to the power wire in the data connection lead so power can only come out of that case for the data connection. If someone connects a second PSU nothing bad will happen.
It's the only practical way I can see of doing it.
Though I am not clear on the scenario where some member of the public might try and connect a second PSU, even accidentally.
It's the ones lugging Van de Graff generators behind them, who have a USB Zapper in their pocket, an evil glint in their eye, you have to worry about.
