No, you cannot convert a 509 Mach V street helmet into a 509 Delta V snow helmet.
No, you cannot add a heated shield to the 509 Mach V street helmet.
The shields and heating element are what set these helmets apart from each other.
The Delta V helmet has a 12V port on the left side to power the shield, featuring an Ignite dual pane heated shield for fog-free performance. This allows the helmet to be directly plugged into a machine to heat the shield.
Additionally, the Delta V shield with the heating element attaches differently than that of the Mach V, making it incompatible to switch shields and add a heated shield to the Mach V street helmet.
