How to add Majora's Mask to other texture hacks?

[Mapa]

Hey,

I am a total noob at this and I have just started playing/installing my first few texture hacks. But I am having trouble with combine two texutre's at once (if that makes any sense). So basically what I want is this toon link presented in bigsharkz video here:

I know it consists of Pinstripe toon link by Monkunit
(http://i971.photobucket.com/albums/ae192/Synthro_/Tuxedo%20Toon%20link/th_ss-712x593.jpg)

and

SkullKid (Majora's mask Hi-res) by DrPanda
(http://img268.imageshack.us/img268/5880/al1006150516.th.jpg).

I know that because in SkullKid (Majora's mask Hi-res)'s description states:
"(Also added BigSharkZ's Majora's mask import, to save downloading multiple files)"

So basically my question is how to "import" the majora's mask .pac onto the pinstripe .pcs?

Once you put the Majora's Mask .pac in game, it effects all the toon link costumes as well.

Basically, Toon Link will always be wearing Majora's Mask, no matter which costume you choose.
