[DnD 4e]Looking for obscure rules loophole

[Smirnoffico]

I don't even know how this happened, but I'm participating in a DnD 4e game.
My DM says he's found a way to embed warforged components in normal living races (practically creating implants) and challenged me to find it as well.

I'm not very fluent in DnD 4 (like at all), so I need help (asking for help is fine by the rules of the challenge).

This way is compendium-compliant, which means no house ruling or items from some adventure. It is a way to mass produce implants, so it's not a class feature or power (like paragon self-forged). I have narrowed the possible solution down to a general feat, item effect or ritual effect. Almost sure it's an item.

Can you guys help me out here?

I'm one of the few people who enjoyed playing 4e in part years ago (even though it's bad, and constant gear checking be dumb), and even then I've no idea on any of this.

Closest I could find was about Shardminds, and thus my guess is ye sculpt one out to look human-like. Course that's not mass-producing, so my wild guess is the magical item ritual in core, or some eberron ritual that lets you do so.
