what if Grisha fought marleyan warriors?

Hello people, here I bring you this theory requested by him. Like the previous topic, I think we have already discussed it. Everything would start when the warriors arrive at the walls. Reiner comes down from the wall to divert the door, but just when he was going to knock it down, something is thrown at Reiner, that was Grisha jeaguer. Grisha gets up, Reiner stands up and would identify him as a changing titan. Grisha would try to hit him, but the armor is very strong and Reiner with a blow would send him flying several meters. Annie and Bertoldo watch from above the wall the fight between Grisha and Reiner, people do not understand why there are 2 Titans fighting, but the fear is greater, it is inevitable that Grisha would lose this battle. Just think that at some point the Titans will be drawn to them and Reiner would be safe by the armor, but Grisha isn't. For what Reiner wins and with the warriors that same day they would return to the Marleyan ships, saying that they lost the titan jaw, but the relevant thing now was to take the titan, believing that he was the founder. and when they put it on the ship they went to look for the jaw titan, but they did not find it, They would return to Marley, where after seeing that Grisha, the Eldian revolutionary was alive, but did not have the founder, they would give pokko Galiard. and they would prepare a second attack for 5 years from now. While Ymir enters the walls, Frieda Reiss would repair the wall. When the Reiss did not die, Crista would not join the army, and neither would Ymir, Remaining. Mikasa in first place, Eren second, Jean 3rd, Marco 4th, Connie 5th, Sasha 6th, Mina Carolina 7th and Armin 8th. They would be cleaning the wall, when the recruits get the news that titans have entered the wall and they must evacuate. The survey corps had come out so the garrison and recruits had to participate. The titan beast walks around the wall and finally comes out seeing that there is no great threat, Eren dies in this situation and Mikasa commits suicide for it, Armin survived. Zeke in his shelter feels the coordinate, along with Pieck he is going to go through the wall the next day to see that there are no more titans inside the wall Maria and the humans have forgotten yesterday's event, indeed the coordinate was used. but where? Zeke would use his latest serum to turn the inhabitants of shinganchina into titans and wait for the founding titan to come. The founded titan comes along with several of the central military police to confront them, but Zeke sets them up and defeats Frieda reiss, Frieda. delivered in accordance with the Tibur-Reiss agreement. Zeke was supposed to take her to Marley, In Marley they put Frieda in a prison. Zeke already having the founder had to find someone not real blood to get Frieda and with his help activate the coordinate and sterilize the Eldians, but there was no one who shared his interests, Zeke spent his time talking to Frieda trying to find something.

Marley already with the 8 titan powers invades the island, although they put up resistance, they were defeated and The island became practically Liberian, where Eldians were forced to work to exploit the resources of the island, and would only depend on Zeke's plan to sterilize or not Do you think the Eldians would have succeeded or the Marley yoke would never end?
