Family reunion twist

 Ok, so we all know that if you choose a mage origin in Origins, the Hero of Ferelden and the Champion of Kirkwall would be related as cousins. I was thinking... if the Warden and Morrigan slept and had a child, then wouldn't that make Hawke the Aunt/Uncle of that kid. Wouldn't it be badass if then they were to meet! 
It'd be the Hero of Ferelden, his son from Morrigan, and cousin/aunt/uncle Hawke, the Champion of Kirkwall. It'd be a family reunion. Would this be possible for the developers to notice this in future games?
