A new idea for a versus event

Since the first Vs. event just happened (Dawnbringer Riven vs. Nightbringer Yasuo) the idea of having skins released as rivals and an entire event around the two opposing sides fighting it out, choosing a side and participating in special missions got me thinking: Is this gonna become a new thing that Riot starts doing? If it is then here are a couple of ideas for some rivals and some skins they could do:

•Diana (Lunar Eclipse Diana) vs. Leona (Solar Eclipse Leona) •Zed vs. Shen •Jinx vs. Vi and/or Caitlyn •Rengar vs. Kha'zix •Garen (Demacian Garen) vs. Darius (Noxian Darius) •Ashe vs. Lissandra vs. Sejuani

• Skins should represent each tribe (Avarosan, Winter's Claw, and the Frostguard) •Jayce vs. Viktor
• Skins could be Hextech vs. Chemtech •Morgana (Vengeful Angel Morgana) vs. Kayle (Righteous Angel Kayle)

Don't be too picky about the skin names, it's just for a rough idea for what the skins could look like.

If anyone sees this, comment which one seems the coolest, give some ideas and concepts, and if your creative post some drawings. Thanks for taking the time to read and I can't wait to see what you guys come up with.
