I don't think it's been done, so go ahead! One thing I would recommend, is you make multiple versions. For instance, it's quite easy to get the Gravelord Sword as soon as you're in Lordran and roflstomp the game, but that could leave you with stats you didn't want. So you could make a version with Str only, Dex only, Str & Dex, Int, Fth, etc. Just many versions with different stats left at base.
Also, I think we already have some farming tips (on the wiki especially), but you could slip a few words here and there on the fastest way of obtaining upgrade materials. For me, now, the most time consuming thing isn't making my build, it's upgrading all the gear again.
