Updated and sort-of-simplified design:

Also available as XCircuit PostScript file:

Note that I still don't want to risk yoking the supply outputs together completely, and I want to draw no mains power when there is battery, and essentially no battery current (microamps at most) when running off mains.

Thanks for all the suggestions: I'll let you know how it pans out...
