Cheers for downloading my awful mod, it's a first, so i do hope it doesn't go /too/ disasterously wrong. :^)

 You'll have to have Danse as a follower to equip the Buzz armor on him without commands, just give it to him and press T to make him wear it.
You'll need to find a set of Buzz power armor, you can get a free set from a power armor station on the Prydwen.
Find Danse and trade so you can equip it on him. The Buzz armor will replace his original armor.
Don't forget the hood! It's the icing on the cake! If his hood has been lost, type 'player.additem e1a39' to add it to your inventory, equip it on him the same way you would the armor.

credit to bethesda for giving me the meshes and original textures to base from.
