It is fine to mix them front and rear.
I work in a BMW dealership and recently we had a customer who wanted to know if swapping to non run flats was approved, and as we couldn't give a definitive answer we emailed BMW technical, and their response was yes it is fine and they said the best way was to swap in stages, with the rear axle first, and then the front at a later date.
