My advice would be good luck. Lockes are popular, and since Egglocke is different enough from a regular Nuzlocke, I'd allow it to have its own thread. But like I said, it'd be popular, so if you're not around to trade eggs very often, I wouldn't make it, or assign trusted participants to also send eggs out to other players.
Also, I recommend making it for XY only, or BW2 only. Making it for all wifi compatible games would be a huge hassle because you'd have to have a bunch of eggs in more than one gen and that can get annoying.
