[What if...? Episode 4] Could Doctor Strange have resurrected Christine instead of trying to erase her death?

Could Doctor Strange have collected the infinity stones and snapped Christine back to life, thereby resurrecting her after her death without erasing it from the timeline, thereby not creating a paradox?
Or even just have obtained the Soul-, Reality- and Power stones to do it? I can't think of a reason why he wouldn't be able to do this, given his knowledge of the stones and what they are capable of, his immense power and teleportation ability (allowing him to take it from anyone, anywhere) and him already possessing the Time Stone, which would make getting the rest easier. Does some law prohibit this?

Probably, but he was letting his ego steer the boat on this one; he went full commit on his plan, developed a severe case of tunnel vision, and crashed the universe.

If he admitted defeat in using the Time Stone to make the action happen, he might have regrouped, cooked up a new plan (like snatching Christine's body/soul out of the past and bringing it into the future, so she'd be effectively dead for the time in question and not trigger a paradox), and then tried a new angle. But that would first require admitting defeat, and the guy who says "Dormammu, I've come to bargain" a half-trillion times isn't the sort to throw in the towel.
