For the league of legends idea i think the CTF version of this plug in could be tweaked a little to make the "towers" from league of legends. The lives count for returning the flag to your checkpoint could be used for "damage counters". Instead of taking the red flag to blue over some distance they tap the same point, that area would be both red and blue flags. Say 50 lives to destroy it will require 50 taps by the players on the "tower". It would be possible now to do it but you wont be able to have more than 1 tower. There should be more than one tower and a "Supertower" at the end for it to be more like league of legends. The pvp aspect of it is to stop the other player from destroying the towers and the winner is which ever team destroys the last tower of the opposing team. At the start of the session you will mainly kill monsters and attempt to kill players to get gold and upgrade items. The general idea is to take over zones which take time to do and cant be done if your getting hit by the opposing team. Dying alot will normally make you lose the game in general as you have to run back to the towers while the other team is destroying yours. Dying to a player will give them a large gold bonus which would normally be about the amount of 6-10 monsters and more if that player was on a kill streak. they use gold to buy upgrades which in minecraft could possibly be potions, food, stronger weapons. You would start with nothing but a little gold enough to buy a core item (wooden sword,axe etc) For this idea the plugin would need a separate economy for inside the pvp arena that gets reset each time you start. Also Just an idea i have no idea how it would be done but make the towers shoot arrow with dispensers that are locked so players cant take the ammo and they shoot when a player is near by. Infinite ammo for them would be included so you wont have to refill. and the mobs would take tower damage and attack you.. i believe its possible to do zombie spawning and pathing options for the player to set but could get messy.
