One thought that occurs to me. Have you looked in the PS Magazine archive to see if something similar had been addressed? The Sgt. Halftrack column comes to mind. Here's alink to get you started:

Seems only possible with repolarizing the generator and swapping out the gauges. If it was upgraded to an alternator, nope.
I'd like to see what happens if it was slave cable started...

Also watch out for your regulator. If you've got the solid state regulator you'll blow it if you try to hook it back up the 'right' way. I don't know how the mechanical regulator will react.
Ask me how I know.

Yes, the SS regulators will not tolerate even a moment's reverse polarity.
The mechanical ones will follow the generator if it is polarized first.
