There are hundreds of Lv inserts out there for sale.
Funny thing...just being green makes them several times more expensive than a normal black insert.
The cheapest gen green insert I've ever seen over the last three years has been 350$, most are 4-500$
I made one using a cheap eBay insert from Hong Kong and a gen pearl a few years ago...but sold it. It looked spot on too, at least from the front or mounted in the watch. Gen pearls are hard to come by in the 166&& series, but doing that is cheaper than buying the gen. My TC is a plain 16610 instead of the LV for this reason, and I have a gen insert installed. Your new LV rocks SSteel! Look forward to seeing her finished.
