Now you're saying they
both didn't raise them, that's certainly not the implication you were going with earlier.
And even in that brief window, they had the kids for at least a year or two, more in some publications like
Children's Crusade where they show them clearly being at least 4-5 years old, when I'm pretty sure they were at most 3 in the old comics.
In that time, they were a family. Wanda and Vision were their parents, trying to degrade that fact is fucking mental. You end up sounding like this:

'She took care of them'
Even if they were fake, which with Billy and Tommy being here now means they weren't all that fake, the two of them thought they were very, very real. And the pain of them disappearing and effectively dying was very real.
Heck, in
Avengers Assemble, part of Vision's bitterness is the fact that he felt betrayed by Wanda over the kids' issue. He lost his emotions when Pandemonium took them, so he couldn't react back then. If he had to react later, which some other comics did explore, he had the same pain.
Trying to say they both felt nothing, or they both didn't invest emotionally into the two kids in that brief time, is fucking terrible and mindboggling. And saying that that investment and that pain isn't as 'real' because of genetic and biological reasons is inhuman.
And as far as the conception, it was a clumsy mess because Englehart was a weird man who seriously wanted his android-human family and was going to do it by hook and crook. I've read the miniseries, it is awkward and fucking insane that they not once ever consider adoption, but there you go. As for the conception, the lead-up to it shows Wanda being...
adamant... that she wanted Vision's kids...somehow...and Vision did plant that idea of using magic in her head earlier in the issue, but after that, she kinda decided that yup, all the demonic energy in Salem, that partially came from Harkness having been burned at the stake,
that was totally the appropriate kind of magic and situation to make a pair of kids.
The panel(s) for the conception/manifestation were quite suggestive (Englehart you are not a subtle man are you):
But yeah, if we take it that Wanda warps reality to the point of being able to bring back the dead, or changing a planet's whole history or what-not, then if it's suggested to her to do something, and she takes up on that idea, yeah whatever, it's possible.
You know this is partially why I'm pretty fine with the MCU's version of Vision being clearly techno-organic, hell of a lot more wriggle room.
Edit: I love this one panel in JLA/Avengers where
Red Tornado takes out photos of his adopted kid to show Wanda and Vision and
then, only
then, do they consider the logical conclusion that maybe,
just-maybe, adoption's a good idea if they really want a family. Omfg.
