Given that this was done based on a pitch from Nolan and Goyer, I'd say he'll have a good bit of influence. Also, given that WB are willing to bend over backwards for him now, I don't think we can under estimate.

We're overestimating how much control Nolan has over this flick
Nolan is only credited right now as an executive producer. He may offer guidance but his influence and control over production is not that significant in that role. Usually when you see a big name given that credit, it's more a marketing thing by the studio than anything else, to give that film credibility with fans of the genre.
He's Alfred.

Having him play Alfred would be a good way to link the franchises without having Bale. He could do a cameo turning Lois away from trying to interview Bruce.
"Mr. White, can I have a raise?"
