Interesting changes to Smites

This would open up a fair counter-play scenario for junglers. The difference between all of the other smites and poachers it is highly unrewarding in the enemy jungle only granting a bonus 20g and others like challenging and chilling smite make ganks and dueling easier. My idea would be A) Increase gold reward of large monsters in your jungle by 10g. If you're in the enemy jungle it should grant you 6x the value of the 10g, heal for 5% of missing health/mana, and grant 175% movespeed decaying over 2 seconds. OR, option B) Create even more diversity among the 4 types of smite that creates a more interesting stake, like possibly baron and dragon. What my second proposal would be is that poachers deals 2x damage compare to the other smites on monsters. Sure this may be overpowered in many scenarios but it would really give it true meaning, and not every champion would get it because it doesn't suit every champion. It may need tweaked but thoughts?
