In an effort to have my cake and eat it too, I came up with: Weilan post-canon fix a different timeline for baby Shen Wei and Ye Zun by yeeting the Rebel Chief into the sun. Their alternate versions still find each other later because they always do. They live a totally different story, but it doesn't matter because the original Weilan already had theirs.

I have no more details and no intention to write it (this would be a behemoth of a story!), but at least I'm satisfied. xD
