New Golems/Nether Villages

Make a new type of golem which is stronger than the regular iron golem and add villages in the nether that contain either piglins or a new type of villager. The new golem would be made with gold blocks in the shape of an iron golem with a diamond block in the middle and a jack o lantern as the face. This golem would also be stronger than a regular iron golem and would defend the piglins or villagers against a new type of enemy which raids their villages. The new villages could look similar to overworld villages or they could be made to have different nether themed structures that make them exciting to be found by the player. It would also be cool to have nether ships that spawn with the villages and they could be similar to the end ships with the elytras.
