Sure that works. I have right now a 5 volt and 170 volt simple dual power supply operating that uses that idea.
Added a zener-shunt regulator to the 170 v output. Look at http://www.mpja.com See their power transformers. Each has two primary windings for the purpose of operating from 110 or 220 v. But, you can mix and match those windings to make it do some unorthodox things, for quite cheap money. Just get a variety of them, then keep track of how warm or cool they run, and use your head when it comes to loading. Lots of possibilities there, just don't burn 'em up or start a fire, and you'll be fine!
