Combining images from different atlases into one image

Hi!

I have 3 atlases, the first one has hairstyles, the second one has clothes and the third one has the character’s body.

Can you please tell me if it is possible to take an image from each atlas, put them in the right order and position, and then create a single image to put it into a sprite or gui?

This is to ensure that when the character is taken into transparency it is a single layer and you can’t see the character’s body parts underneath the clothes and hairstyle.
