New map concept - Getting henchmen to fight for you

So I've been thinking about a new map, with a completely new gamemode, where the goal is to destroy the enemies ''lifetree'' only trough minions and monsters. Let me explain.

• The map: On the northeast side of the map, there is a brickroad. On each side of The Brickroad, there is this ''Lifetree'', that works exactly as a Nexus, only that it has the look of a tree with some kind of prism in it. Champions may not interact with the Lifetree, The Brickroad, or creatures on The Brickroad whatsoever. There's also two sides of the map, and in the middle of the two sides, there's a river, which you can walk over. There's two pits in the river. In each of the pit, there's a dragon, one blue and one red. On each side, there are a lot of jungle camps. In each camp, there's a number of minions or monsters. The minions and monsters grows stronger each time you kill them. It takes some time for them to respawn though. The respawn-countdown will start as soon as all the minons or monsters at the camp are killed.

• Objectives: Whenever a champion in your team kills the last minion/monster in a camp, every minion/monster that was in that camp will spawn next to your Lifetree on The Brickroad. They will then start moving on The Brickroad, towards the enemies Lifetree. As they get close enough, they will start attack it, in order to destroy it. They will only stop before that if they meet enemy minons/monsters and the road, and will then fight them. If your minions/monsters win, they will continue their journey towards the enemy Lifetree, only to stop if they face more enemy henchmen. Whenever you get minions/monsters from a camp on the enemy side, you will be granted extra gold, and the minions/monsters will spawn at your side of The Brickroad, with a small boost of defence and attack.

As you're not able to interact with anything except the jungle, then your biggest goal is to kill as many jungle camps as possible, because THEY will destroy the enemy Lifetree for you. You may still kill enemy champions, in order to prevent them from getting any henchmen.

There will be ordinary minions and monsters in the camps, such as Caster Minion, Siege Minion, Gromp, and so on. Blue Golem, Red Lizard, The Dragon, or Baron Nashor may not be in this map though.

''Special'' minions and monsters that could appear:

• Healer minion: Can't attack, but heals nearby minions and monsters.
• Mage minion: Attacks as Caster Minions, but will also sometimes cast a AoE damage spell.
• Tank minion: Can't attack, but has alot of defence, and forces enemy minions and monsters to attack it.
• Three-headed Wolf: Can attack three enemies at once, one with each head.

The two dragons, that appears in each of the pit:

• Blue Dragon: If your team succeeds to kill the blue dragon, your Lifetree will permanently grant a small boost of health, armor and magic resist to every ally minion/monster on The Brickroad.
• Red Dragon: If your team succeeds to kill the red dragon, your Lifetree will permanently grant a small boost of attack damage and ability power to every ally minion/monster on The Brickroad. (You may have the both boosts at the same time. Max 5 stacks of each boost. None of the dragons will fight for you on The Brickroad once you kill them, they will only grant these boosts.)

Smite will be removed from this map, to make it a bit harder. The same goes with all the jungle-items. New Summoner Spells may be added. New items may be added.

Of course, any of these ideas can be changed. It's only this concept I'm trying to show. The concept that you must in some way get henchmen that will destroy the enemy Nexus for you.

So, any feedback? How does this concept sound? Anything that should be changed? Something new that should be added? Give me all of your ideas!
