Well A4 is really just another V4 morph pack, so yo could have just added her to your V4 :-)

Do keep in mond though that morphs are additional coppies of the characters object geos. The fully loaded Cr2 for V4A4 (all v4 and A4 morphs loaded) is about 73 meg the "un-injected file" is 1.2 meg. Makes a big difference how many morphs are loaded :-) Makes a big difference on how much ram you a using too.
