I'm genuinely surprised Universal didn't at least have a small line of vintage-y shirts with the old USF logo on them. Nostalgia is a powerful thing for some people, so I'm sure they would have sold. And if they had gone the whole nine yards and produced shirts or pins with original attraction logos or themes... well, I would have spent a lot of money on them. They may not have sold a ton of "Alfred Hitchcock: The Art of Making Movies" shirts, or "Earthquake: The Big One" pins, but I'm sure there would have been a market for them of some size.
