Wouldn't it be easier to allow weapons finess feat to allow Dex Attack/Damage as a selectible on/off like Power Attack. This would allow dex based builds to build up from lower levels and not invalidate all the dex AC builds currently slated for TR or packmuling at go live.
Not quite appreciative of the scenario as you describe it, but we could work a similar design out quite well; As an example:
"Improved Weapon Finesse: [Feat, req: Weapon Finesse, Dexterity: 21, BAB: 6] or [Enhancement: Ninja Spy/Thief-Acrobat: Req: Weapon Finesse]: Benefit: All finessable weapons (Or short sword/staff, for respective enhancements) and thrown weapons now use dexterity for damage."

Then, add in a tier 5 innate for Shadow Dancer that allows finessing of additional weapons. That'll give it the unique element, while still preserving the potency and early level use of finesse.
