My take on the subject is this. Dubro or Sig flat-bladed nylon pinned hinges fit nicely into the slot left behind by removing CA hinges. They are not prone to occaisional failure and glue every bit as positively as CA hinges. I no longer use CA hinges on anything larger than a .40 size airplane due to the fact that I have had a CA hinge crack everytime I did use them. If you are going to cut the controls away, then use the flat nylon pinned hinges. If you remount new CA hinges then sometime in the future, maybe in a few flights, maybe in 100, you will get to do it all over again.

As far as doubling up on CA hinges, you are also increasing the workload of the servo.
