How to make a player spawn with a package on? [closed]

Hey. I'm working on a team capture the flag type game, with a similar concept to Overwatch, as there are characters you can choose from. So, I was wondering how to, when the player deploys, override their appearance to a package. I took a model of a package (that had a head and such), added a face, changed the skin tone of some parts, and put it in ReplicatedStorage for the time being. How would make the player turn into this model? I know I'll either need to make a custom character with animations and all, or create some sort of weld script. Please help, thanks!
