Poacher's Knife?

So, I guess we all know Poacher's Knife is, for now, the smite upgrade that noone gets, and for good reasons: it only gives you an advantage in the enemy jungle (and even that advantage is not that good), and, it also informs the enemy team of your playstyle (aka: "he has poacher's knife, he's sure to invade...") Well, i for one, would like to see this item see some play, so, here are some ideas for changes to it:

1. Increases smite damage by 20%, if you kill a large/epic monster while the enemy jungler is around (as in outsmite him) you get bonus gold/%maxhp heal/ms/all of the above?
2. Smiting a camp in your jungle gives you a stack of Poach, up to x stacks (mby 3, mby 5?). Killing a camp in the enemy jungle by using smite uses all poach stacks to give you gold and %maxhpheal/ms/both?
3. Killing a camp in the nemy jungle by using smite places a mark on that camp untill an enemy champion steps on it. While the mark exists, it stores 1 gold per second/per x seconds (up to a cap?) and prevents the respawn timer on the camp from starting. When an enemy champion steps on the mark, all gold stored is awarded to the player (the one who put the mark in the first place, no confusion here)

As you can imagine, the first idea would make it into more of an objective challenge smite, which could actually be played and useful, while also being useful when counterjungling, and, the second change would preserve the idea of counterjungling, but would actually make it more viable by making you not basicly need to spend your entire game in the enemy jungle, but peer in and steal a camp from time to time, and cashing in on cumulative bonuses based on how much time you spent in your own jungle, and finally the third change would preserve the idea of heavy counterjungling playstyle but would also make the item way more intersting and not just a worse version of Ranger's Trailblazer.

This are my ideas, and i would like to hear your opinion on them, and maybe your own ideas, because i am sure most people, and not only myself want to live in a world where all items (and champions for that matter) are usable:)

Cheers.
