#3 One main eventer on SmackDown could lose their spot

In the pandemic era of WWE, the two top stars on SmackDown have been Braun Strowman and Bray Wyatt. While we're not specifically namedropping anyone, but Big E becoming a main event superstar could mean that it would be at the expense of another.
This is, of course, taking into account two assumptions - One, Big E stays on SmackDown, and two, he remains a babyface. If Big E remains a babyface from the start of his singles run till he becomes a main eventer, then there's a high chance that one main event superstar from SmackDown goes down the pecking order.

It all depends on the timing of the push and if he were to gain momentum while one top babyface loses momentum, it's not hard to imagine a situation where he outright replaces said babyface.
The only exception to this would likely be Roman Reigns, who will remain a top babyface till the day his career ends. He shouldn't be replaced, either.
