I think it would be pretty cool to see champs in a wedding line w/ the married couple being a poll of our favorite ship between champs. Other champs could be wedding roles like best man, ring bearer (Ammumu, but he drops the ring) , wedding crasher (Gragas) , maid of honor, flower girl (Annie), and a clergy.
could be a recurring skin line too!
EDIT: Zac & Riven is my ship XD
Priest Karthus skin when?
Best bet for a couple would probably be 
+ 
, since they have king/queen skins already. Probably the only semi-cannon married couple. Otherwise, maybe Kat+Garen? I can just imagine Kat throwing bouquets everywhere.
Though I'd honestly rather have it be a skin line based on a scene, like... Runaway Bride 
where she was getting married to someone she didn't want to, and the splash art is her running out the chapel doors with the crowd/groom/priest all behind her.
Either way Priest Fiddlesticks, with doves instead of crows, would be legit.
Maybe groom Shaco? With surprise proposal boxes? xD Bard also kinda works.
For Xayah Rakan maybe
Using non-canon ships would be a bad idea because ie if champs X and Y get the matching skins but some users ship X with Z, they'll feel pretty bad.
Skims that aren't necessarily paired would be cool tho. With different wedding garb depending of the region of the champion receiving the skin.
