If a 'team of 5' story came out, which region/faction would you want to see?

Hey guys, the question is the title but yeah

So if a story about a team of champs (Think the old bilgewater GP rework event style of story) what region would those champs be from? what would their challenge be?

for me it would be a tale that takes place in Zaun and Piltover, the five champs would be Jayce, Ziggs, Vi, Ekko, and Ezreal. They'd likely be doing something under the radar that cait would be more or less... directly opposed to. and it would involve fighting against both Viktor and Singed, with exploration of side story of vi/ekko and jinx, as well as with ziggs as the loose cannon comedic relief

As a side suggestion Gnar and kled short story where kled goes to eat the little yordel and then gnar goes mega, with stupid chase scene entailing
