Gen IV to Gen V to Gen VI?

So I have a platinum ROM and I decided to be nice and use it to catch shiny pokemon to send out on Wonder Trade to brighten up someone's day.

So here's my plan;

1. Catch Shiny Pokemon using an AR Code for Shininess
   
2. Upload the pokemon to Pokecheck and select "Convert from Gen 4 to Gen 5"
   
3. Download the .pkm file and edit out the premier ribbon
   
4. Convert to Gen 6 somehow?
   

My only problem is this; I understand that Gen VI no longer uses .pkm files. Has the hacking community thought of a way to convert .pkm files to the new format yet short of actually having Poke Transporter do it?

PKHeX can convert Gen 5 PKM files to the new PKX format, but there is currently no way to inject .pkx files to Gen 6.

I see! Are there AR codes then I can generate?

There isn't even an AR that works on 3DS games​.

Well there is one called the Powersaves 3DS. But not AR though

The only way I would guess this would be possible, quickly and easily is with a legit copy of Black/White/Black2/White2, Gen 5. Create the Pokemon you want to release on the Wonder Trade on something like Pokedit, then queue them to your Gen 5. GTS them, then Bank them, then release them on the Wonder Trade?

you need a retail cart for any Gen V game, in order to transfer to Gen VI.
