I've experimented with a two-crew type system before (Red Team for feature development, Blue Team for stability and bug fixes).
Rather than treating these as fixed teams, we treated them as workstreams that people rotated between every sprint (every two weeks).
It worked for about 3 months, until it didn't - by then we had grown enough to organising the teams around the business capabilities or domains instead.
