You don't need to get Genesect, Keldeo and Manaphy to get the shiny charm, from what I remember. The easiest way to get the rest of the legendaries is to offer on of yours on the GTS for a legendary of the list. It'l trade pretty fast, believe me. Then you'll set up the one you got from the GTS for another one you're missing and so on. That's how I got my own shiny charm.
