I just want a FF11 modern game.

My thoughts on this are that FF11 could just be put into the FF14 engine so that it's more playable. I've thought about how that could be done and I don't believe it would really be that difficult if they use the right method and only change the client by molding it to interpret FF11 data, especially given FF14 and FF11 share similar concepts like linkshells, autotranslate, guilds, etc.

A lot of conversion work would need to happen such as creating FF14 actions for the menu actions in FF11, converting quests, upscaling textures, but probably a lot of that could be automated in 2025 with convert programs or AI. We can right-click targets in FF14 so it's not impossible that could be adapted to contain all the battle actions rather than just Attack, for people who prefer it. As for character customization, there are a number of ways that could be gone about but just choosing an FFXIV version of each part selection would be the least work, even if the races are ever so slightly different.

It isn't that simple. FFXI is still developed on the original PS2 devkit... You can't just port a 25 year old legacy codebase into the mangled ARR spaghetti monstrosity and expect it to work. At that would it would be easier to delete everything and start over.

Not only that but a lot of systems are so different that this couldn't and shouldn't work. You can't covert FFXI's AH into FFXIV's infinitely worse marketboard. You can't convert Galka and Mithra into Roegadyn and Mi'qote. The combat systems are incomparably different. There is no GCD in FFXI. Physical and elemental damage types don't exist in FFXIV. Skillchains, magic burst and well, basically any of the interactions between abilities that exist in FFXI don't exist in FFXIV.
