I would find it really interesting if you couldn't enter Windhelm as an Argonian or any cities as a Khajiit. You would be allowed in sometimes (e.g. I have a message from Riverwood. About the Dragon attack) or if you had completed the main quest ("I'm the Dragonborn. I've saved all your lives twice."). There could be a questline to allow Khajiit (and Argonians) into cities - you go the Jarl and do a quest to prove Khajiit can be trustworthy and then a couple of Khajiit would buy a house and not do much. I think that would be relatively easily codable, but it would be a bit annoying.

If you weren't Khajiit, you'd have to convince the Jarl and/or a number of Thanes. Possibly once you'd completed the Civil War you could have a word with the leader and say, "Let Khajiit/Argonians into the cities."
