Changing skin during a map via script

Is it possible to change the player skin via scripts? I mean, the map would start with certain player sprites, and at some point would be changed after picking up a "disguise" item. I don't need to activate via this item, because it's a one time thing on this map and I'm going to activate the whole thing via thing action script execute.

Thanks in advance

I've never done it before, but after some research I turned these up:

I hope these help :)

Thank you very much!
