You might try adding an Army poncho liner to your bag. I've spent a zillion nights under the stars in Alaska with an extreme cold weather bag and a poncho liner. Gets too cold you can throw in a hand warmer.

I have the Wiggy's FTRSS made in Grand Junction. It's a two bag system. Give them a call and they'll tell you everything you need to know about two bag systems. Especially if you speak to Wiggy himself

I'm not sure why you would want to carry two sleeping bags, unless you already have them and can't spend any money, which I can totally relate to.

Modularity allows flexibility through all seasons. Why carry more bag than nessesarry or less bag than required?

The poncho liner is essentially a quilted rectangular bag liner that is much more versatile. Combined with a poncho it makes a great ultra light summer sleep system. I'd say stick a poncho liner in your zero degree bag and try it out. I'll bet you gain 10 more degrees with it.
