This thread shows a SeaRider with 4 single pods.
If you put the console forward a bit, you could make the back ones doubles. I'd use a narrower console and a single jockey for that layout, but it would give you 5 seats. Thinking about that arrangement for mine.
With a 30" wide console, you might want to think about how easily you can get up front if you need to.
I don't think there's room for a single jockey and two bench seats though (but then I didn't think there was room for side-by-side jockeys either!).
Good luck with the project - send pics when you're in progress.
