I like Kendall and McKenzie, but they would probably end up being called Kendall and Kenzie. I like that, too...just something to consider. I also like Brynn.

Those are all super cute names but I think they're getting pretty common (some people care about that, some don't--IMO it'll be like the Jennifers and Kristens of our generation.) But if that doesn't bother you my faves are McKenzie and Payton. GL!
THIS! They sound very nice together. I like Brynn too, I haven't heard of this one before. Maybe you can incorporate all the ones you like in the middle names. Like Kendall Brynn and Mckenzie Payton....
