Will Astral Luke have a cameo?

I heard that Luke astral-projects himself into the past to warn Han not to conceive Ben Solo.

Han will heed Astral Luke's words and a Days of Future Past event will undo The Force Awakens and The Last Jedi.

The film supposedly ends with a scrawl of text: "And so Han proceeded forth, met Princess Leia many years into the future, married her and told her: "I don't want kids."

Leia, heartbroken, called him a "Scruffy nerf-herder" but eventually agreed that they would just adopt an ewok. Everyone from the original trilogy lived happily ever after, Rey spent the rest of her life rotting away on Jakku since her destiny was no longer in existence in the new timeline; since there was no First Order in the new timeline, Finn ended up being a worthless nobody; Poe ended up being a nobody; Ackbar lived this time; Luke became a real Jedi master and all was right in the galaxy.

The end.

.......Hey, just let me dream.
