I would compromise and just get a full length webasto-type sunroof fitted instead. Far cheaper, you can probably get it electrically driven and you will still have the good looks of the 406.
I would be wary of converting a 406 to full drop top. On the one hand you might have an elegant drop top similar to the RR or Bentley Mulliner drop tops (encl). On the other hand, it might look a bit odd and boring. It is the reason why the convertible versions of cars like the RR Silver Shadow had the 'coke bottle' style over the rear wing to add elegance and interest to the design.
