Why don't you all leave this guy alone. To each their own! There are plenty of people who don't use their Jeeps for what you guys feel they must be used for. Maybe he likes the looks and the freedom, who the F cares, it's not your money. I'm sure each of you have mods that others think are worthless or look stupid. In fact, I recognize a couple names in here with mods I do not like, but it's not my Jeep, and we all have different tastes. Isn't that the best part about our Jeeps? That there are endless ways of moding them to look different? Whether it stays on the road, or hits the trails. Whether it's done for looks or purpose. Everyone is guilty of at least a mod or 2 that was done more for looks than purpose (not that it may not have a purpose, but many times people on here won't use it for that purpose).
What I'm trying to say here is can't we just all get along? We all have something in common, love for our Jeep. If you really feel the need to post, can't you just say "sorry, not something I personally like, can't help, but good luck on your search!" ? Whatever happened to, If you can't say something nice, don't say it at all. Bullying has become such a disgusting thing in our country, and as someone bullied as a kid, I can't stand to see adults continuing to do it, and see no issue with it.
Yes, 22" wheels may not provide the best comfort or ability while off-road, but maybe he won't take it off road, you don't know. Just give him the heads up! Rant is over, so I'll start my post.
OP, I'm sure you're aware, but the larger the diameter of the "fixed" portion of your wheel/tire combo (being the wheel), the less "flex" you'll get out of it (being the tire) while off-roading, specifically with rocks. But if that is something you're not interested in, then you have nothing to worry about!
As much as it is not my thing, I have seen some larger wheels that I have thought looked good. In my opinion, the less spoke-like the wheels are, and the less empty space you can see through them, the better I think they'll look.
Here's a guys build I think looks very good!

@CxLxC must have deleted the photos, but I remember liking them. Maybe you can get in touch with him.
Good luck on your search!
