how would I make a player morph admin command that turns you into character name in folder?

I want to make a admin command that morphs the player into a character in a folder via the name of the character with multiple characters in the folder. How would I make it to read the characters name from with the folder? I know it'll be something to do with clone but I want to know.

for example: :playermorph me Boony or :playermorph me moomi or :playermorph Mit1140 Boony (Boony and Moomi are 2 of the characters names in the folder)
