There's another way this can be done, although I can't help with the technicalities of it.

You can create two buttons with your global JS, and set each to paste in the full code for each of your sigs. Then, when you want to use one or the other, you only have to click one of the buttons.

The main downside is that you would be pasting the whole of your signature(s) each time, rather than a neat template.

A friend made me a version of this a while back, but that was for monobook and pasted in templates (which, as for Coronatus' solution, would mean having to make a template on each wiki you edit)

Sorry this isn't a detailed reply, maybe someone else can work out the JS if you need it :)
