Sorry if the code wasn't very clear, I wanted to show the idea in a small piece of code, "TheNameplate" was an example of any nameplate I intercept and work with. I get the nameplates with an OnUpdate that runs only when the number of childrens of the WorldFrame changes. This is my PlateProcess() function if you are curious:

local NumChildren = -1
 
local function PlateProcess()
  if WorldFrame:GetNumChildren() == NumChildren then return end
  NumChildren = WorldFrame:GetNumChildren()
 
  for _, Plate in pairs({WorldFrame:GetChildren()}) do
    if Plate:GetName() and Plate:GetName():find("NamePlate%d") and not Plate.Scripted then
      if Plate:IsVisible() then Plate_OnShow(Plate) end
      Plate:SetScript("OnShow", Plate_OnShow)
      Plate:SetScript("OnHide", Plate_OnHide)
      Plate.Scripted = true
    end
  end
end
 
SpyroTest:SetScript("OnUpdate", PlateProcess)

Yeah I already did this and the change applies, but now after the explaniation of zork I know why I doesn't show anything.

On my code I do a ThreatRegion = GetThreatRegion(Plate) and then I work with ThreatRegion, but your idea definitely looks better performance-wise and design-wise, I will implement it. I already add information to the nameplate to mark it as "seen" the first time I see it, so it will be easy.

Thanks for the info, it's impossible then. I will do the color changes in the nameplate border then, it's and addon for Arenas for altering the nameplate of enemys that are out of combat, to do flashy things like Shadow Dance->Sap and I thought that showing the threat texture in green to show the "out of combat status" would look pretty cool.
