Harrowing Easter Egg? 6 shadowy champions!?

Someone mentioned this on another post i did.

Has anyone tried to go into the new map mode with the 6 champions surrounded by shadows all at the same time? Example all same group?

Example (Twisted Fate, Cassiopeia, Xerath, Hecarim, Leblanc, Zed, Lissandra) one team with all these champions!?

Message me in game if you want to try it to see if it reveals anything.
