Ages of Jaina and Danielle Kieran?

I know Dani Kieran is an apocryphal character, and even if they do somehow include her in canon, she probably would end up not being Han's long-lost daughter. But I was just thinking how a meeting of Dani and Jaina would be, and what their ages would be.

And if she did somehow end up as Jaina's half-sister, would that make up the loss of Han's sons at all?

I would assume that if Han was 30 in ANH, than Dani could be at most twenty years older than Jaina (thinking that Han got around starting at 16 or so)

 

She was likely conceived before Han met Leia, so she's at least a decade older, if not more.
