Bob - DO it.. productize it. If you get the price and features right it will probably outsell the rest of your offerings. If it in fact is truly redundant it will be a huge hit. I had something similar on the notebooks, but decided I was too busy to bring it to market. Yours is more elegant than mine was, but same principle. I like the fan, but what will the target weight be...

Currently all the superswitches wiring and regulators add up to 6-8 oz. Can't imagine it being heavier than that. I would think you could even save weight.

I would LOVE to eliminate having to run 2 switches, 2 regulators and all the spaghetti associated with it.

I am currently using 2 independent "trunks" if you will - 2 sw, 2 regs, 2 batts. I have never had a problem with it but its a royal pain to route all the wires... and it looks like crap.
