Hi,
There´s no problem considering you observe a couple of things:
-The AP must have local Country Code in order to keep it in compliance with local regulatory domain. Then, you need to permit that Country on your WLC.
-CAPWAP tunnel have some latency requirements. Depending on the link´s quality you´ll may face AP disassociation from WLC.
Wireless Cloud solution like Meraki is probably a better option on this scenario, depending on how bit is your sites.
-If I helped you somehow, please, rate it as useful.-
