I removed Materia Blade requirement in exchange for sword requirement in both versions. But I beefed it up to give auto haste and regen. I also gave it a higher weapon guard % for FFT vanilla (where I used the innate weapon guard ASM). I gave him innate two-hands for the same reason you did. In FF7 he was a jack of all trades, so I also gave him a decent MA stat. But I slightly changed his skill set depending on the version.
In FFT Vanilla, I just used formula 42 to keep the theme of Limits being dependent upon damage done to the user.
I then made each skill unique, but tried to keep a resemblance to FF7.
-Braver being a decent damage attack on one enemy within 3 spaces
-Cross Slash had less range, but hit a cross shape
-Blade beam hit in a line up to 6 tiles
-Climhazzard was point blank, but high damage
-Finishing Touch I kept as is, since you can't add status effects to formula 42
-Meteor Rain had the same area of affect as original, just with formula 42
-Omnislash hit around Cloud, similarly to a draw out skill
-I repurposed cherry blossom to be full map hitting spell that one of the lucavi used.
In WotL I took a completely different approach, and used the 2D formula, but gave the skills MP cost to prevent abuse.
I did this to all the sword skill (while also reducing sword WPs) to prevent ROFLStomping enemies.
Cloud had Move-MP UP to help him still be able to get enough MP to still use his skills. You just had to be smarter about which skills you used where.
-Blade Beam was changed into a ranged skill, but used Dark Knights formula for Abyssal Blade. This made it work more like it did in FF7, where it hit the first enemy hard, and then hit nearby for reduced damage.
