4 Seasons Xayah/Rakan

I recently saw a seasonal Xayah/Rakan concept on a "leaked" concept document. I have no idea if the doc was real, or exactly what the concept entailed, but it sounded really cool. Both Rakan and Xayah could choose between 4 different forms (spring, summer, autumn, and winter) instead of having 9 forms like Elementalist Lux. If you pick matching seasons, they would get a special seasonal recall. Autumn Xayah + Autumn Rakan = Autumn Recall with them dancing in fallen leaves. Winter + Winter = flying into the air on a toboggan/sled. Autumn Xayah + Winter Rakan = nonseasonal recall. Having 5 different recalls, depending on what seasonal skins the champs chose, would make it equal in value to Elementalist Lux.
