My bank in Australia, Commonwealth Bank, recently refurbished my local branch as a "flagship" branch, lots of TV advertising about how awesome the new experience is, etc. I thought nothing of it until the other day when I had to go to the bank. When I went in, someone greeted me about 5 seconds after I walked through the door, asked what I wanted, took me to the right counter and explained what I wanted to the person behind the counter (there was no queue - but that might have been good luck). I was completely blown away by the service. At the moment I don't think any deal from any bank would tempt me to switch.
So yes, I think UX innovation could add a lot of value to the generic bank experience.
