I think youre correct on most of that but you're also not taking other design factors such as friction and head loss, and most importantly velocity into consideration. So it isn't as simple as splitting a 1,000 gallons per minute amongst two lines.
If they don't have enough water pressure to run Low-E at the top as it is, it is unlikely they can maintain operating pressure on both simultaneously regardless of how the withdrawel is split.
We had a similar pumping capacity and at times charged multiple lines near the summit (sized appropriately) and at well below nominal flow rates we could barely maintain 200 PSI. As soon you try to charge that much more steel the physics change.
So in summary, if Witch is top fed (I think it is), I don't think they would be able to withdraw much water on the upline.
Last year Sorcerer and LMC came back to life, this year Vertigo. Maybe next will be Witch to Black? Mystery after that? Bringing stuff back from the dead is awesome. I love to see it, options are good!
