Mirror Turn Signals Upgrade??

Have a USA Gen 3, Trim Level 4 Prius. I like the safety features of the turn signal lights on the outside mirrors of the Persona models.

What would we need to do, to get this feature on our Prius?

If I got some of the Persona outside mirrors, any idea how much wiring would be necessary to make them work on my Prius?

Or are the mirrors compatible such that we could add just the turn lights themselves to the existing mirror assemblies?

etc.?
