No, not just merchandise starring Wario himself (because that seems to come with every Mario related toy line), but merchandise based on actual Wario games, like those in the Wario Land or WarioWare series. What merch do you want to see?
Personally, I want to see some nice toys/action figurines and maybe plushies, of characters like Captain Syrup, Rudy, the Shake King, etc (from Land) and Mona, Jimmy T, 9 Volt and Ashley (from WarioWare).
