Sure, but you only run 15a through it. Sometimes you are required to use
#12 to avoid voltage drop.

As many as you want. However, it will obviously still be good for just
200a.

As long as the neutral runs with it, I don't see why not. Someone could
object that it violates a basic requirement that devices only be used for
the purpose they were intended, but I can't see why this would be unsafe;
assuming it is done reasonably.

Obviously you have to beware that you don't overload the circuit, but aside
from that it is fine.
Just beware that long circuit may be subject to problems and those problems
can be hard to find.
My house had one GFCI breaker, and they put 4 bathrooms and 3 outdoor
outlets on it. When one outdoor outlet went bad and created a ground fault
it was a real trip to find the problem; especially since I didn't even know
it was on the breaker.
