program redirect of links

You could also use a _remap() function in your controller to lookup the correct information and perform the redirect.

Not really in this case. If you visit id/2 and you do not have a controller named id and method named 2, the router will not know to which controller to route to, and fail to hit your _remap() in your base controller.

I wouldn't put a _remap() function in the base controller. In fact, I think that would be a bad idea, because most of my controllers have no need for a _remap(). I would create a controller named Id with a _remap() function to point it wherever the calls need to go. If I needed to remap more URLs than just those with 'id' in the first segment, I would make more controllers.

If this was a significant problem, I would create a library to rewrite the routes and override the router to load the library. However, that would be my last-ditch approach, as it indicates that all other attempts to fix the problem have failed.
