Swapping hair?

[VoldoVega]

I am a noob to modding and experimented with just renaming some of the hair files under pac/edit/hair (example, replacing hair_00000 with hair_00001).  Then go into CAW and test by choosing the swapped hair. It works for the short hairs, but when I try it with a long hairstyle it CTDs. Same results when trying to swap entrance wear with in ring items. (The idea is to trick the game out of restricting certain items for your CAW, and put the restricted model into a non-restricted slot so they dont conflict anymore)  I got it to work with regular items. Would this involve extracting and injecting obj/yobj files into pacs?
