Unlikely, since they said that they weren't going to be doing those anymore a few years ago because they kept failing.
Mordekaiser rework: one of the most broken champions the game has ever seen before or since.
Kog'Maw: How can we tell if he's cheating? Undo the biggest thing we did.
Syndra: got basically of her changes later changed again/reverted.
Malzahar: has had to be updated like 3 or 4 times since because he became busted as a support.
And not to mention that every item that they worked on has been changed in some way, shape, or form since. They simply realized that mass updates like this for champions wasn't sustainable, and that they would need to take a closer, more in-depth look at each champion individually, assessing what the core issue was for why they were considering an update in the first place, and then fixing that core issue.
