You'd need to take a serious hit on WS gear to maintain it.
Edit: Maybe not looking at it, but you would still need a serious amount of STP during TP phase: Tactical, Goading, White Tathlum, Rose Strap, Hoard Ring - the works.
You would be able to get away with just using Rajas, Unkai Haidate +2, Brutal Earring for WS though, and not really worth it inside Abyssea anyway (Although you probably wouldn't SAM in there anyway, just an fyi).
