Is there any canon based proof/foreshadowing that dany will end up as rhaenyra 2.0 or cersei 2.0? Is this just certain shippers dream?

lol none that i can think of. Cersei parallels are especially way off base, and she is in fact closer to Rhaenyra than Daenerys is. Being the sort to “never forget a slight”, “quick to anger”, wears armor, fights for the throne in spite of the men who want to keep her off it, paranoid, a lover on the kingsguard, associated with a Strong known for violence (Rhaenyra had Harwin, Cersei has Robert). Even the gradual weight gain is something the two share. There are precious few things Daenerys has in common with Rhaenyra, and at least two of those things are “she’s a Targaryen” and “she’s a claimant for the Iron Throne”. 🤷🏻‍♀️
