Coiled coiled coil...triple helix?

I've seen similar questions asked a bunch of times (how to wrap helix along curved path, etc), but nothing applies to my problem.

Consider this image:


I know how to model something roughly similar. Create an Helix, then a small circle cross-section, then Sweep it with Twist along Path and some turns.

What I need to do, is take this and make it follow the path of a bigger helix.

Hence the title, coiled coiled coil.

I have searched all over for a way to do this, i.e. make a Helix follow another Helix's path.

Ideally I want to extend this concept to X number of coils.

Once I make the Sweep/Twist along Path, I would think I could Sweep another circle around the first sweep, but it just doesn't work.

Is this even possible to do in SW 2014?

This is driving me nuts!
