How about more champions have something unique in game?

After the recent juggernaut update we've seen the crystal spires of Skarner, the dragon's ghost by Mordekaiser... Are there plans about more champions having something similar unique to them during game? It's been one of those times you can say "this champion brings something unique into the game" which should be developed further, if not from the solo presence of a champion then from pairs (like the PROJECT skins are making the machine-minions appear if there are 3 or more of them on the same team). Ghost can appear in the jungle with multiple Shadow Isles characters, Baron having an interaction with void characters, the announcer saying "An enemy/ally has been deleted" if someone's got one-shotfrom a Veigar ulti, outter or inner parts of your side of the map covered in snow with the presence of Freljord champions in your team, there are endless posibilities here. And these examples are only cosmetic-wise, I'm also talking for stuff like the new champion updates that have an impact on the game.
