ToME: the Tales of Maj'Eyal

Is there an any way to get back to default character tile mid-game, if you set custom tile on character creation?
In character save, in game.teag, mod.class.Player file has a line: "d["has_custom_tile"]="npc/humanoid_human_blood_mage.png""
But does deleting this line really change character look back to default?

I ain't tried but I assume oyu gotta get rid of that and add in whichever d["moddable_tile"] and d["moddable_tile_hair"] ya want
