Illagers hold more items on raids

It would be cool if in raids illagers could hold more items in their off hand. For example, maps, like the illagers were trying not to get lost while going to the village. Another item could be the goat horn when it comes out in 1.18. This could also drop from the illagers, because the goat horn makes the same noise as the raiders. Also it would be interesting if some pillagers could spawn with unique fireworks that show the shape of an illager head, and can also drop them, but that is the only way to get them. This would be a small tweak but would add to the lore a lot
