Is it possible to change player packages in R15?

I have been working on a customization menu for a little while and I wanted to use these 2 packages for male and female.

But the problem is, I cant find any API anywhere that shows how you would go about converting a players package. Does anyone have any links or tutorials or even advice that could help me out?

Thank you for your time.

@incapaz is completely wrong. It is indeed possible. If you ever equip a package, then you will know. I have made a youtube video on it. Here's the link. https://youtu.be/yeEb4Cl00L8

Here's a text explanation.

1. Create a script
2. Create PlayerAdded and CharacterAdded functions
3. Place a wait after characteradded
4. clear all the CharacterMeshes in the character's model
5. Equip the boy package on your profile
6. Play the game
7. Copy all the CharacterMeshes that are in there
8. Create a folder named bin inside of the script
9. Create a folder named boy inside of the bin folder
10. Create a giver

You can create a giver by

local character 

local itemstoclone = script.bin.boy
for _,v in pairs(itemstoclone:GetChildren()) do
v:Clone().Parent = character
end

The same can be done to add the starter girl you want too.

Hope this helped.
