I haven't seen anyone build that on her but the answer is no. She doesn't need armor penetration that much and CDR os sort of a non-issue you'd sooner run out of mana than suffer from Tumble or Condemn being on cooldown.

Attack speed and movement speed on activate is good but phantom dancer has better critical damage and attack speed while ghostblade has attack damage and more movement speed. Lastly Phantom Dancer has more critical strike.

Generally speaking Vayne doesn't really want this item but it lets you build AD and for a hundred gold cheaper it's almost appealing over Phantom dancer in a duel, chase, or escape. With Blade of the Ruined King you can sort of combine activates to prevent anyone from escaping your grasp.
