Lore Question

I been talking to my friend who is into Necrons amd we had a theoretical talk about Necrons closing eye of terror and argument being yes with necrons trying to do that during war in heaven. My question is, with all blackstone pylons destroyed by Abbadon not just on Cadia but as said on many planets, and Eye of Terror now grown into way bigger size than it was during the whole war in heaven, can eye of terr9r still be closed by necrons?
