Pictured is the Y-Wing I made out of my kids' Duplo about 18 months ago. We were building away and I decided to see what I could make from their limited collection. This turned out better than I'd anticipated, so I took a few pics and did a comparison with my 7658 Y-Wing. I hope that you don't mind the fishy ion cannon or the square astromech.

And yes, that's pretty much the reason I shared this MOC. I'll show him when he's old enough to see ANH - he was about 15 months old in the pics and will be 3 this summer. In other words, I probably have a couple of years before he'll be interested in the movie.
