Rogue pretty much can't be in Apocalypse, unless there's a future scene that takes place in say 2023, give or take say 10 years. In other words, it's very unlikely.
In 1983 she isn't even born yet.
Since she was shown in the 2023 Wolvie wake-up scene we know that the events have played out, at least generally, the same for her.
We can definitely assume she has the same powers since she was wearing the long gloves when she held Bobby's hand in that scene.
There are a couple of possible stories where I could see Rogue, but they are all unlikely.
One is a Mystique spin-off that would take place in the later 1990's, and in this timeline (which could be the same timeline as the Wolvie wake-up scene) Rogue is Mystique's foster child. Part of the story could even be Mystique convincing Rogue to not let go of some person who has super strength, invulnerability and flight powers. There's nothing to say that the Rogue in that 2023 scene couldn't have those powers... Anyway, this spin-off story could be based on something like the Books of Destiny, making Destiny a new character, and it could even include Mystique's own team that could be a Brotherhood or even the government sponsored Freedom Force, that could lead to the government sponsored X-Factor.
The second would be a cross over story titled the X-Men versus the Fantastic Four. This would likely become a possibility after the F4 reboot fails miserably, as I'm expecting! Anyway, in this story 2025's Kitty has lost control of her phasing powers and her molecules are destabilizing. The other X-Men are away, so fellow team mates Iceman, Rogue and Colossus (and maybe others) take Kitty to Reed Richards. Reed has the ability to help, but for whatever reason, won't. This creates an epic battle between the F4 and the X-Men. Maybe Doctor Doom shows up and is willing to help the X-Men. Story plays out, the two teams work together and defeat the baddie. At the end the X-Men could do the following:
Create a new X-Men team located in Europe titled Excalibur. This could be either a movie or a tv series and could include Captain Britain (surely that's a shared character), Meggan, Pete Wisdom and Wolfsbane, along with OT Nightcrawler maybe. Anyway, the whole Aurthurian thing can play into it, Colossus' sister Magik could be part of the story at time, etc.
Anyway, although I could see Rogue in some stuff, as explained above, there's almost no chance she's going to be in the Apocalypse movie, and it's also unlikely we'll ever see her in a relationship with Gambit!!!
