Palladium Bi-retrograde Perpetual Chrono?

For all the Roger Dubuis experts and collectors here, did Roger Dubuis ever execute the  Bi-retrograde Perpetual Chronograph (Lemania Caliber) in Palladium?  

He did use palladium in his earlier pieces. If there was a QP Chrono in one, I haven’t chanced upon it yet - but from a feasibility perspective he might have.

Are there any good resources in this regard? When it comes to Roger Dubuis' early pieces?
