Between $10 and 15. Shimano.

I just checked a 32t cassette against a 160 mm rotor and that looked a bit close, so I'd go for the 203 mm on 38t.
Probably more effective bronze welded to the back of the cassette than zip tied to the spokes.
The regular spoke protector doesn't prevent chain drop, it just catches it before it chews the spokes or jams the freewheel. You'll need it far enough back that the derailleur doesn't hit it in normal operation.
Appreciate the useful responses, grumpus.
Inner diameter of centerlock rotors seems to be 35mm and BCD of 6-bolt rotors is 44mm. I was thinking of using bolts, nuts and washers to setoff the 6-bolt rotor from the cassette and then attach to cassette and spokes to maintain position.
Even if the centerlock rotor fits the freehub, it may interfere with the derailleur, as you warned.
