Rush1, as discussed previously, John Dunlavy's designs required careful tuning of the crossovers to match individual drivers. This was important, in part, to maintain time/phase which he considered so critical. The matching was needed within a given driver model from one manufacturer, let alone when changing from Morel to Vifa or Scanspeak.
I cannot imagine it would be too difficult to mount Scanspeak drivers in your cabinets but it would also require a rebuild for your crossovers. Because of the matching requirements, I don't believe the crossover diagram for the Scanspeak version will get you all the way home. So again, I'll suggest you look into having your Morel drivers repaired. And as I also said, Miller Sound would be a top recommendation for that task.
Good luck.
