You had indicated this is a high visibility network and hence, any changes unless you are 100% sure that it won't cause any disruptions you are better off scheduling the changes to be implemented during the maintenance window.

However, AFAIK, enabling CEF switching in the router s/b non impacting unless the code you are running is vulnerable to any severe CEF bugs. With the powerful processing capacity of modern day routers the router s/b able to build the CEF table pretty quickly and no impact s/b felt.
