Trait Overhaul Mod by Bienchen.

I'm not a modder, but I've heard them say that if there's a mod doing similar things that they'll cancel each other out. They can't separate and create stand-alone codes for most things, so consequently they have to overhaul or override the existing codes for things like traits so it can be individually modified. That's why some mods won't work together, because both are overwriting the same code.
So based on the descriptions, I'm 98% sure they would conflict; sadly. But this is just a opinion since I don't have the Personality Please mod.
Hope this helped. Real sorry if you already knew all this! Just thought explaining what I heard might help you.
