You know what try some thing new give him a sleeping pure white dragon of aegon ancestor who was sleeping and becomes a stone over a period of time he will be much bigger then the baelon the black dread and instead 2 legs he will have 4 his name is Albion the Vanishing Dragon White Dragon Emperor 😁
Wouldn't laena be better for him as she has vhagar and corlys is richer than lannisters and rhaenys is more likely to support him as his children will be trueborn
