This gives you a couple of options to improve the base chat icon. I got the idea after seeing some recent chat icon mods.
Place whichever pk3 you want into gamedata/base:

ImprovedBaseIcon - My modified version of the base chat Icon, where the speech bubble
actually points at the character.
Animated shaders are based on a shader by Ruxith in SiLink's custom icon:
