nope but switching weapons is probably one of the easier things to mod in FF7 PC.
Can't remember how to do it exactly but it involves recompiling the battle.lpg coz you need to add an extra texture for the sword, i think clouds texture goes up to rtad or something so you would then convert the texture to the proprt format, and rename it rtae and add it to the folder where you extract all your file, and you just swap one of the sword files out for the AC sword. I probably wrote somethin abot it a while ago, check one of ultima espios threads I think i wrote something near the start.
