I don't think this is a bad idea, it might look quite nice. The arguments I foresee coming are:
- How many people connect to that many networks to make this worthwhile?
- Why on Earth would you need or want to connect to that many networks/servers, as you couldn't possibly keep up with them all.
I don't think a lot of people do connect to that many networks, and from all the screenshots I see, I don't think many people make use of the multiple-line capability in the switchbar. I am completely at a loss as to why anyone would need to connect to that many. However, I use 3 networks and that's 2 too many for some people so we all have different uses

I wouldn't mind seeing it personally.
