Fingers for two chords

Bdim/E  I like to substitute a diminished chord with the dominant 7th a major third beneath it, omitting root notes. The notes in a Bdim are B D F Ab. Looks a bit like a G7alt, right? (The notes in a G7 are G B D F) . You can play the Bdim/E as a G7 barre chord with a low e root. Also don't play the high e string or use your pinky to fret the Ab on the high e string:
e  x or 4
b  3
g  4
d  3
a  5
e  0

D6b9 I would play as follows:
e  5
b  4
g  4
d  4
a  5
e  x

All that said, the reason Georgia sounds cool with all these funky chords is the voice leading, so if you are just trying to drop in and out of these chords without the correct motion it will probably sound goofy.
