Get a tool called MorphManager, load up the character however large the file and delete the morphs you don't want from it then save the result (actually a big text file) as a new character. It's out there someplace! However, I haven't used it in ages but I did once make some morphless figures for pose testing and for de-morphing poses. I don't know if it works with the new texture format in P5/P6 but it could handle mutiple figures in a set in the same file.
