This is nothing unusual - or new - quite a few of dance pros already "work for the government" by being involved in various schemes that are aimed at getting people fitter by encouraging them to take more exercise. A lot of schools now have dance classes as part of their curriculum, with various pros visiting on regular basis.
I agree with Jeremy Vine, Arlene would be perfect - not everyone wants to learn ballroom dance, but many would get tremendous fun with stage dance.
