I think it's not a rework since those are too much teasers. But SHOULD it be one, it may be for, and here was my first thoughts upon seeing them :
 * : Since Garen loves Demacia and SO much, it creates conflict considering the fact that Katarina is from Noxus, rival of Garen's beloved city. So Garen's heart was shot and let loose a burst of green energy, pertaining to emerald, that lets him realize that he must have understanding of the situation and choose.
 * : Sona uses music from her precious etwahl that gives harmony to her team (as a Support, where her abilities aid in different ways). On the other hand, she is a mute and the shot in her throat let loose white energy, pertaining to opal. HARMONY here refers to internal calmness and that is what Sona needs to fight her worries as a mute.
 * : Zed is too hungry for great power. He was blinded by the strength that the shadows gave him and soon he fell to evil. He even murdered 's father who happens to also be his whilom master just to get what he craves for. All he need is purification from the darkness and become cleansed in the inside; he gets easily blinded by power, which always leads to bad things. The shot in his eye, or head, let loose a burst of blue energy, pertaining to sapphire, and it gives him what he needs: purification, an aspect of DIVINITY.
 * Vi used to live in the streets with her former gang, and needed brute force to survive. A sudden turn of events made her want to be an image of justice while still being legally able to beat up baddies. Yet Vi held on to her gauntlets too much; she apparently believed that her body was innately weak because the Hextech gloves would always be found in her arms. The shot in her chest (presumably the pain reaching to her arms) let loose a burst of red energy, pertaining to ruby, and bestowed her VIGOR: active strength, energy and determination that flowed throughout her human body, no more, no less.

There's my crazy theories about the teasers but I don't even know how "Deadeye" relates to Taric (in my wildest dreams, Taric will probably be gameplay-wise updated to an  but it's too far from reality). But as I was saying in the intro, the hard work and amount of teasers are usual for hinting an upcoming Champ; in this case, he is currently named by the fan community (including me) as.
