Hi Hanno,
We understand the need, but right now we have no plans to do this for 11 specifically. There's some cool stuff on our pipeline regarding running different versions of Service Studio in your machine, but we'll announce it later.
In the meantime a possible workaround is to change the shortcut icon (e.g. shift+right-click on the icon on the windows taskbar while Service Studio is closed, select properties, select change icon) and get creative.

Thanks,
Tiago Simões
