Thanks for pointing this out. I got my first AJ Styles shirt (long overdue) and Shinsuke shirt. It's too bad the womens' merchandise isn't better. I'd really like an Alex Bliss or Becky Lynch shirt but they're not so great. And you can't get a Bayley shirt unless you want to dress like a 7-year old girl (or a John Cena fan).
I would actually show him some more mainstream stuff. The "classic old" matches are going demonstrate some good wrestling, but without all of the big production I don't know if you could hook a new fan. Get into all of that later.
