Pokedex Completion- All the tradebacksies

[Qui]

Okay so I'm trying to finish my pokedex and it's really flibbin flabbin difficult without a partner who has moon because I'm a lonely butt. -breathes- 
Right now the only things left I need from the Moon side is...

x Lunala
x Pheromosa
x Celesteela

And when I check the GTS, they all want the same thing. Solgaleo or Tapu Koko. 
I adore my Solgaleo to bits so I refuse to trade Nebby away for good and well Tapu Koko...
I don't really want to part from him either. It seems like a booty to get him back. :c

However, I am willing to use Nebby for tradebacksies.

Meaning is there anyone that is willing to let me borrow their Lunala, Pheromosa and Celesteela for like... Two seconds? Just so I can trick the game into thinking I'm an avid competant collector who isn't only doing this for a Shiny charm? ;~; I'll be trading over Nebby(Solgaleo) as a buffer so you don't have to worry about me suddenly running off with your moonbat or anything.

edit:

Also by the way! If you need pokemon that evolves through trade I'll be happy to help there too! :D I'll send over Nebby so you're pokemon can evolve then we can do some tradebacksies.~
