I'm not that big on "rock" bands anymore but yes something focusing on first 2 - 2.5 albums would not be to terrible. Love Grohl more as a drummer than as front man but I would prob see them but have to be heavy on first few albums. Probably not as likely.
This would be a great example of a great Foo set:
