You can purchase additional miles, but you need way too many to add up to 50K. You can only purchase a fairly small percentage to complete your "purchase" of a reward ticket.
Your only decent shot would be if CO brought back a reward seat sale like they had last year. IIRC Birgmigham or some other non-London city. I'm sure someone will correct me on the correct city.
