If you get the Missing Props error then it means your npcs.big isn't where it should be. Make sure it isn't named npcs_big.big and that it's in the Dead Rising 2 / data / models folder.
Theoretically you could upload the npcs.big for every model mod, but it's 460MB and for those who know how to do it themselves, as it's not hard, rather just download 3MB of files and replace them themselves quickly.
Also, playing as females is always somewhat awkward in the cutscenes because of the voice and the skeleton glitches. Deviant bride is the only model I saw so far with only minor issues in cutscenes.
or just use minazuki's mod (backup) but crop scenedescription's geos (backup wanted? done at 1st bit already) and completely replace/delete chestdefault.big/tex (backup ditto above) and creating a copy of tammy.big tammy.tex in the same folder level (npcs) renaming the copies as chest_default.big/.tex, pack up npcs.big, replace over their current models/npcs.big. VOILA and wearing ninja outfit allows you to keep the same image but be a ninja!
