Cosmic Reavers Vs. Dark Star / Super Galaxy Vs. Dread Nova.
With everything going on with themed PVP Bloodmoon and PVE Invasion it's only a matter of time before Riot dives into other themed matches. Two of these seem kind of obvious:
1.) Cosmic Reavers Vs. Dark Star 2.) Super Galaxy Vs. Dread Nova
Would like to see 5v5 or even 6v6 matches on a skinned Summoners map like Bloodmoon and Arcade has done, but even more refined.
The Cosmic Reavers seem like the light side where as the Dark Star champs play like the dark side. This way you could end up with the Summoner's Map divided between a Cosmic light side and a Void dark side.
When I think of Super Galaxy champs I think of them as truly intergalactic defenders whereas Star Guardians are more concerned with protection the local system of Runeterra. The Dread Nova would come in like space pirates of sorts and be the direct antithesis to the Super Galaxy champs.
New skins I'd like to really see come out of this would be the following: 1.) Dread Nova Kled 2.) Dread Nova Urgot 3.) Super Galaxy Anivia 4.) Super Galaxy Quinn 5.) Cosmic Reaver Sivir 6.) Cosmic Reaver Katarina 7.) Dark Star Aurelion Sol 8.) Dark Star Talon
For the SR reskin of Super Galaxy Vs. Dread Nova I'd think the Super Galaxy Space Platform being boarded by the Dread Nova Pirate Ship would make an excellent division of the SR map.
