Iron golems can be repaired with different metals

Iron golems should be able to be repaired with different materials. any material weaker than iron should make the golem weaker, while any material stronger than iron should make the golem stronger. the material fills in the cracks or creates a cool design. Here's a list of the materials that could repair the golem (other than iron)

• Netherite
• Diamond
• Copper
• Gold
• Obsidian
• Emerald
• Lapis
• Amethyst

I think this would add some sort of realism to Minecraft. Please consider this.
