1. What makes you so sure a boy would automatically love those things?
2. Are you not "forcing your likes" onto him if he doesn't? What makes it so different than "forcing them" onto a girl?
Traditional gender roles are bullshit and 99% informed by society. My homeschooled cousin was for the most part not exposed to said roles and she DID play with Toybiz X-Men and He-Man and shit. You're also overlooking the fact that most kids aren't going to like the boring musty old shit their parents liked in the first place. They have new, more exciting shit targeted to them that will actually allow them to relate to their peers. Imagine how your son's first day at school might go...
Other kid: Hey, have you played the new Fortnite Season 22 update?
Your kid: N-no, but I know what a Toybiz X-Men Trevor Fitzroy action figure is?
tl;dr: stop trying to push your interests onto your kids in the first place, period. If they show a natural and organic interest, sure, you can give them stuff from your collection. But specifically saving your collection up to give to them makes a loooot of assumptions.
