$2200 is a small price to pay for a pair of 802Ds (assuming you like the sound!), so my suggestion is to grin and bear the premium of the original part. B&W makes their own drivers, so anything you try to replace the original with will be a deviation from the design and would require changes to the crossover (definitely) and the cabinet (likely).
I don’t see a remotely acceptable option other than writing the check for $2200.
Good luck!
