Details are light though. There's nothing that expressly says that "This product will let you edit your existing save files", just talks about customizers and "available" edits to "Powersaves". I just don't think this is going to do what you want it to. Or what I want it to for that matter.
Wonder Trade is actually a good way to approach this problem because the injecting (once we have a tool) will never hit anywhere near Nintendo's reach. They can't see that the incoming pokemon is edited, so in theory (unless the game itself is doing the legitimacy checking) we can have whatever we want transferred into our own games. That's great news for people who want to see favorite pokemon from other games.
If someone feels like going online and trying to troll people with their tricked out Luvdisc, well, so be it. I guess we need to come to grips with the fact that we live in a world where you can't go online and talk to strangers and expect them to play fair and treat you nicely. It should come as a shock to nobody that Nintendo has failed to cure society's ills.
