You could, but I think it introduces more complexity which just is going to get 
in the way of building a good GUI.
The main benefit I see by taking an always-vnc approach would be that everything 
becomes 100% networkable. There's nothing getting in your way because you're doing 
things on a remote machine. And you even get the same look&feel you got from 
the local connection because it's the same tool connecting you.

My current thinking with GUIs is that network transparency is more trouble than it's worth.

The problem is, simple things end up being overly complicated. You can't just pop up a file dialog box to select a new CD-ROM ISO because you can't browse files on a remote machine. Instead, you need to have something like a "pool" concept or something like that.

But yeah, maybe it does add too much complexity. I don't know.
