I hope your non-NA Eevee is the female DW ability - some are hard to get, and not a single one of my Hidden Grotto finds is a female so far. Kind of disappointing.
If you have something nice to offer, I can get you a Lv.50 Shiny Eevee. I will admit I've triggered a bunch into my SS using AR (in the same fashion as the Event itself that gave them away, but without Wonder Cards and unlimited in quantity), but they are otherwise perfect Event clones and will let you get a Shiny of whatever Eeveelution you want a Shiny in. The Japanese Ditto meanwhile is from a trade, and if I send you one I'd be cloning it.
