I would try all the other things Jimmy mentioned first, THEN if all else fails trying to get them to eat pinks using different methods voluntarily, I would then just SCENT ONLY with anoles. Then you can gradually "wean" them off the lizard scenting to regular pinks. This way they don't ingest any possible parasites from the lizards if un-frozen, and the lizard scent can be more easily replaced with the scent of a normal pinkie too.
I have had some super stubborn kings in the past go quite a long while. If they still have fairly decent body weight and are not to the point of getting thin yet, don't worry too much. They usually all come around,...some just take alot longer.
Only when it has been many weeks and start to get thin do you need to take matters into your own hands and force-feed to keep them alive until they develop an initial feeding response.
Good luck!
