Don't create a new group or organization within your company whose job is "innovation". This takes various forms, but it happens reasonably often when a big company gets into product trouble, and it's hugely damaging.
First, you send the terrible message to the rest of the organization that they're not supposed to innovate.
Second, you send the terrible message to the rest of the organization that you think they're the B team.
That's a one-two punch that will seriously screw things up.
