So Cersei shouldn't be his wife and Twyn and Rhaella I doubt they will allow it, if not someone who gives him benefits ummmm Elia would be the best thing for Rhaegar since it would bring Dorne closer and they could help rebuild Sumerhall, if he makes a great friendship with his brother I doubt he will not support him, even if he finds out who is the real father and Elia does not seem like a woman obsessed with the throne. I doubt Twyn, Aerys, and Rhaella would take a chance on Olenna, she's too dangerous. But Melora Hightower is an option. Leyton Hightower doesn't play the game like Otto Hightower. Another would be Catelyn, although the lands of the Rivers do not seem very important to me. Either Lyanna Stark who would give him all the support of the North, Ashara or a girl from the Crown lands like a Velaryon from a secondary branch who would provide him with a powerful ally within the Crown lands. I sincerely vote for Lyanna ha ha ha, there is no good story with her and a Targaryen other than Rhaegar. Another thing if you raise Dragons you could hide them in the Rock and when they are big enough give everyone a good scare.
