Golem Age Variations

It’d be cool if Minecraft added a “golem age range”, golems in villages would vary from the “default” golem and 2 variations of golem that had more moss indicating how long they’ve been defending their villages (Ig. like adding a mossy beard or scars). It’d be cool if player made golems and golems that spawn from scared villagers wouldn’t have moss (since they’re “new” golems) and that with time they get mossy, kinda how copper ages in Minecraft. I don't know, I feel like the golem hasn't had that much attention and it'd seem nice for MC lore.
