The simplest way to prevent groundloops in taildraggers would be to take the wheel at the back and put it in the front, just under the engine, then stick the main wheels a bit further back to compensate and get the whole thing to balance upright with the C of G forward of the main wheels. I'm told it's been tried, and with some success apparently, although much of the fun of flying is, of course, lost.
