Using AirLoopHVAC.clone by itself won't work. Instead you'd probably have to get the loop's supply components, clone them individually and then assign them to the new loop. This can might be tricky for components (e.g. water coils) that have connections to other loops.

I would consider an alternate approach in which you build your original loop in the measure, and iterate that code for the number of loops you want. I've found that way a lot cleaner than trying to fully duplicate existing systems.
