GH1 battery grip or similar...any third-party options?

Hi all,

my GH1's grip has always been a touch too small, or rather the camera itself has always been a touch too small for me. A grip, like the classic battery grips for DSLR's, would be great.

I've searched the forums but surprisingly found no threads about this.

Anyone have any ideas or recommendations for a GH1 grip? Maybe I could screw some kind of plate into the tripod-mount to add height to the camera.

No one know anything about a GH1 grip option?

I'd be interested in something similar for the GH2 if it ever came out... there were some mockup photos posted somewhere a while ago if I remember correctly - I think from an Eastern manufacturer who was modifying (?) other grips to fit?
