Just wondering why you chose the rather large 13mm size?
That will force you to make a the wheel larger than it otherwise would have been.
Unless you make the wheel huge, I don't see why mounting a light plastic lens would be any less safe than a CBS color wheel.
The CBS wheel (with 6 sectors) ran 1440 rpm, in the 24 fps 6 interlace system.
At 15 fps per second, a Nipkow disc will only turn 900 rpm, and half that if it were interlaced with two spirals that were offset by one-half line width.
