What if Zenn-La created a "Green Lantern Corps"?

Watching Silver Surfer series I wondered what if the Watcher gave Zenn-La more advance warning of Galactus's coming and then gave them the knowledge and means (yes, finding loop holes is apparently what the Watcher does) to create a weapon to fend him off (i.e. ultimate nullifier-ish). After this is done they compact this "nullifier" down to ring/belt buckle/what ever size (think computers and how much one SD card can hold now compared to a few years ago). Then they send them out to "deserving" warriors to help other worlds fend off the devourer of worlds as well as any other major threats to the sector.

Norrin Radd is obviously the first and the one to distribute the rest of the trinkets. Who else would he distribute them to and why.

Would something like this work in the Marvel Universe?

What would happen with Galactus if this came to be?

I would imagine Captain America would be asked to be one of the first to accept this "honor", but of course he would decline thinking it was to "cosmic" for him as he's more a down to earth type of hero.

Spider-Man and Daredevil both come to mind.

Wow! This was three years ago? Dragging It back for more ideas.

I still wonder what kind of impact it would have on the Marvel U. and Galactus.

The "worthy" recipient doesn't have to be from Earth either.
