I'd love this, personally - sets of voice calls from him when encounters are started where he'll name them and call out one or two important features, weaknesses or things to be wary of - as well as taking the egotistical edge off him a little, it would help to sell the game's intention of him having the knowledge of a former archmage, even if his power no longer reflects that.
Yeah, it could provide a unique form of party banter that no other games to my knowledge have ever utilized. Gale could totally freak out and panic when running into the Minotaurs for instance, and other party members could respond in some really hilarious ways. Wyll would probably quip that Gale is really not being helpful right now, and Lae'zel would helpfully point out that everything dies if you stab it hard enough.
