State of Poacher's Dirk

I was looking at the item statistics for the current patch, and poacher's dirk is being purchased in only .08% of games, while Raise Morale the last of GP's three ult upgrades is purchased in .19% of games. When initially introduced Poacher's Dirk was a great concept because you were taking a gamble that you could counter jungle 3 camps. However with the state of lethality in the current meta, junglers like Lee Sin and Graves dont even consider it anymore, with the only viable champion to use PD being Kha'Zix . If the upgraded form was changed to a more versatile item such as Caufield's Warhammer, then it stands to reason it would jump up in purchase rate. This would allow you to get a cheaper warrior enchant on all ad junglers, not just lethality users, as well as allow people who normally wouldn't purchase warrior, (Like Olaf ) to get Poacher's Dirk with hopes of snowballing so that warrior was viable in the grand scheme of their build.

TLDR: Idea to change Poacher's Dirk upgrade from Serrated Dirk to Caufield's Warhammer to make it viable on a wider range of champions.

Just wondering what you guys thought about this idea. I think it would be great for tempo and help you feel more accomplished when counter jungling. Also considering the purchase rate it basically doesn't exist in the game currently.
