They is a million things Scott could do, to link the first film in to these new alien prequels that would be a million times more effective. Like having Ash, The Nostromo, Weyland Yutani, even f**king Jonesy the cat make a cameo... But for f**k sake Scott, why you talking about Ripley's mother? It just sounds stupid and unnecessary and makes the already shat on alien universe even more of a shitty place to be.
As some of you have said it's probably Scott just talking shit and nothing will come of it. But it would not shock me if Scott decided to put this unnecessary stupid idea in his next film, since he as already put some stupid moments in Prometheus and Covenant.
Talking about Alien Isolation.. At least in Alien Isolation, having Ripley's daughter interacting with the Xenomorph is realistic because it's possible that Amanda would wants answers of why her mother never returned home. I mean wouldn't most people want answers why there loved one never came home? Some may just except what Weyland Yutani tells them about the missing Nostromo, were others wont and will start to dig a little deeper.
