Variable Revolve

I wasn't really sure what title to give this question, but I was basically wondering if anyone knows of a better/easier way to create the geometry I needed.

 

We have a machine that uses air bags to lift up one end. I was able to model the airbags in their down position with a simple revolved boss, but I also wanted to create a configuration showing them in their up/inflated position, and since their range of motion on this particular machine isn't linear this is trickier to do.

 

 

I was able to create something that looked acceptable using a loft feature, but it involved creating numerous reference planes, profiles, and guide curves:

 

Does anyone know of a simpler way to do something like this? I thought it would be cool if you could just revolve around a curved axis, creating a sort of variably-revolved geometry (see picture below), but Solidworks doesn't have that capability (that I know of anyway). It's also pretty rare that I have to model parts with any sort of lofts or weird curves, so I don't have a lot of experience creating stuff like this.
