Light mover AND ventilated 'cool tube' reflectors....Possible?

I've been toying with the idea of a light mover but I think that ventilated reflectors are the single most important thing to up the light AND lower the heat. I wouldn't want to sacrifice the ventilation to my lights BUT I cannot imagine how ducting could run to 2 (or more) reflectors that are being rotated in a circle - It's the Sun Circle light mover that has my attention.

Also
How does one work out watts per square feet when using light movers?

Stationary lights are easy to work out.
But moving lights pose a problem for me.

Any advise would be appreciated.
