hfss is a very good tool for simulating distributed elements, such as transmission lines.
If you want to simulate Lumped elements you need another software.
Ansoft has "ansoft designer" that is very good for your purpose. you can import s2p in it and also you can use Hfss results in Ansoft designer.
be successful.
