[@Puppy0] It's not too much of a retcon. Just that Aegon's dragonriding children wouldn't be Martells. Could make for some interesting family dynamics. 

I do hope one of Arianne's children is named Elia though.

Yeah Oberyn and Elia are really a must for Martell children names, I think it would be rather odd if they were something else.
