Cool hack - give it a try!
If you wish to subscribe to my Google+ feed via RSS then use this: http://plusfeed.appspot.com/104405539079062799451

You can set up you're own, copy my URL above, delete the ID and add your own Google+ ID (the bunch of numbers on your Google+ profile address). Then plonk it into FeedBurner.

It's not perfect but not far off.
