“More than making children, I want them to become strong kids. A special power in the father’s genes, or otherwise I want greater strength. And that’s where I think that Ise is the most suited one. The power of the legendary Sekiryuutei. Even if the kids don’t inherit the sacred gear, maybe the kids will inherit the aura? This is a good chance. Definitely, this is the Lord’s guidanceUh! …….I unintentionally prayed and received damage, but that’s how it is. And there’s perfectly no presence of humans here. Let’s try it out once right now. If anything, the faster the better.”

This is Xenovia from volume 4. So it could've went either way with Issei or Shirou but from what we see, she wants children with the aura from the Red Dragon Emperor.
