I also ran into an install similar to yours. My client had a flat network and each wlc had licenses for the amount of APs in a particular building. What I did to make sure the APs never join the other wlc, is to use a Mac list. This allowed me to enter the APs base Mac address on the wlc and I enabled under the ap policy to verify authorization using Mac list. You can also do what AA mentioned which is good practice, but you have a chance that APs might join the other wlc. If the other wlc has different configurations, it might cause issues until the ap falls back to its primary.
As mention above you can use high availability on the APs, basically you will need that one the APs join any WLC you then go to wireless tab, select the AP and set the options of primary and secondary, etc WLC.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
