Set Pre-Luclin Face from Lua

[Eudith]

Hello!

I had the idea of adding variability to NPC names and appearances without having to make many near-duplicate NPC types; the following code works for randomizing on spawn the name and sex of an NPC, but I want to also randomize the pre-Luclin face of the NPC. I can't find a function that does this. Am I missing something or is there no way to do this from Lua at the moment?

names = { "Guard Williams", "Guard Malone", "Guard Baxter" };

function event_spawn(e)
	e.self:ChangeGender(math.random(0,1));
	e.self:TempName(names[math.random(1,#names)]);
	-- How can I randomize pre-Luclin face?
end

Thank you very much!
