Nope. Flawless parents aren't going to help.
First, IVs come from the Method 5 spread. Let's say you just happen to get a partly-flawless spread:
Then each frame for the second RNG changes which IVs come from which parents:
Let's say we want a perfect special spread, so Attack doesn't matter. And that parent A has 31s in HP and SpAttk. We would want this spread:
And we would attach the Power Lens to Parent A to force the second RNG to advance to that frame, the one that gives us the IVs we want.
