Hide Nameplates on enemy casts

[GOTSNUFF]

Is there any way to make it so non-casting enemy nameplates hide when an enemy is casting. There is a weakaura for it but it requires a modifier to hide the nameplates, does anyone know if it's possible for nameplates that aren't casting to hide when enemies are casting automatically?

NamePlates being protected frames and some forbidden, can't be automatically shown/hidden. While this can be applied to the visible portion, the NamePlates' "UnitFrame", the invisible parent frame that handles clicks is the limiting factor.
