The speculation or the concept is a bad idea?
I know in the UK and other countries DEMUs are quite common, with a Diesel generator powering electric motors. It doesn't seem a huge stretch to have a Diesel generator and a pantograph the can pick up power from overhead lines where present, and a Diesel generator as backup where they aren't.
However, I expect every changeover will take a couple of minutes, so it seems pointless unless you have a substantial section of electrified track to run on.
