The ap's you do not want to failover, you should not configure the secondary WLC, but configure a false entry. This way those ap's try to join a WLC that is not there while the others are able to join. I believe you can also configure on the WLC which ap's can associate to that WLC.
I don't know if that will work for you, but if it does then great. like I mentioned earlier, the easiest is setting the secondary controller on the 5 ap's that you don't want to join the wlc during failover to a bogus name. this should give your ap's enough time to all join except for those 5.
