Later Targaryen Culture

Obviously this is a great mod, but I always thought it was odd to portray the Targaryens and Velaryons as High Valyrian from Aegon I to Aerys II. I think that the early Targaryens and Velaryons should be High Valyrians, but after the Dance of Dragons, this should change. After Aegon III, there are no more dragons, and the culture of dragon-rearing was one of the things that closely tied the Targs to their Valyrian Feeehold origins. After Aegon III, all subsequent Targs should be Westerosi Valyrians, and Dragonstone's cultuee should become Westerosi Valyrian as well. Additionally, Alyn Velaryon, being a former bastard, should be a Westerosi Valyrian, and the Velyarons should be that culture from Alyn onwards.

Additionally, as Egg was raised by the Crownlander Dunk, him and all subsequent Targs should be Crownlanders, up to and including Rhaegar. Maybe since Viserys III and Dany were raised in Essos/former lands of the Freehold, they might be closer to Valyrian culture than their more recent ancestors, and they could be the currently barebones Essosi Valyrian culture, or perhaps Pentoshi to reflect where they spent their formative years.

Additionally, the early Blackfyres should be Westerosi Valyrian, but Maelys's generation should be Essosi Valyrian.

I am aware that later Targs/Blackfyres can hatch eggs "like the High Valyrians", but I think this is more like medieval Italians mimicing Romans than a true "return to tradition", so thats why I chose the death of dragons to be the point of culture shift. What do you guys think?
