Here's one of my double bass setup. The hi-hat is attached to the left bassdrum, because I didn't have enough place to put the legs...
The pedals are a few inches apart, but it was still pretty comfy to play. It's a matter of getting used to:
And here is one of my current setup. No double bass, but double pedal. My hi-hat stand is an Iron cobra, so it only has 2 legs wich are also rotatable.
Those hi-hat stands make the life of the double pedal-er a whole lot easier (as you can see):
glad I could help
