Legendary Bloodlines of ice and fire

Hello ! In the vanilla mode we have the opportunity to win legendary bloodlines such as that of Alexander the conqueror or that of Ashoka. So I propose to create legendary lineages of this type, as hard to reach at least.




The lineages I think of:

• The legendary lineage of the First King of the first men. Or since there is debate with the identity of the First King can be done with the Last Hero, to allow this bloodline to the first men and westerosi andals.
  
  Or allow this bloodline only to the personages who follow the religion of the old gods or of the first human cultural group.
  

• The legendary lineage of Hugor of the Hill, the first Andal king who would have met the septs whose father would have given him a crown with seven branches. Allow this lineage to the Andalusian cultural groups and characters following the faith of the seven. This bloodline can give a artefact crown with seven branches

• The legendary lineage of Azor Ahai the warrior of light. Allow this legendary lineage to characters who follow the religion rhllor.
  

• A lineage has YiTi for the characters of their religion with that of God-On-Earth. The founder of the dawn empire predecessor of the Yiti empire.

Bloodlines could have other effects than the legendary bloodlines of vanilla mode like adding an artifact etc...



I'm not asking that all these bloodlines be added, I'm just proposing some ideas that have gone to me.
