Okay then write a scenario where nothing changes
Like write a way in which the same outcome happens but with these admiral’s instead
Pretty easy, if you simply switch the Gorosei and their brainfarts with admirals and their brainfarts.
Sakazuki/Saturn: Just like Saturn completely forgetting that he can immobilize people on the spot and make heads explode, Akainu forgets that he could AoE the island with magma. While chasing the weaker SHs, he fails in bringing in his prey just like back at Marineford where Jinbei escaped with Luffy right under his nose. Then he jumps on the Elbaf ship and gets double-teamed by the Nika-duo.
Aramaki/Mars: Just like Mars Greenbull immediately heads up with his tree powers trying to find the transponder snail. He shows off some neat haki and DF powers just like Mars, but once he goes after Luffy's group he gets gangbanged just like Mars did.
Kuzan/Venusjuro: Just like Venusjuro Kuzan arrives and immediately starts freezing the Pacifista around the shore. He then also goes on to attack the Labosphere, freezing and breaking the cloud it's based on (similar to Venusjuro's slice). Afterwards he quickly clashes with Zoro and gets suicide-bombed by Atlas. In the end the God-haki from Joyboy knocks him out.
Issho/Warcury: Just like Warcury he starts an onslaught on Luffy's group with collectin a ton of rubble and raining it down on them. But just like in the actual manga the giants come to help and block it with their shields. When he's about to do an even bigger attack, the robot arrives and attacks Issho. In the end he also gets knocked out by Joyboy's God-haki.
Borsalino/Jupeter: Nothing to write home about. Both barely did anything the entire arc anyway.
