How do pre-retcon skins fit with the new lore?

Riot has said several times that most skins aren't a part of the main universe. They're alternate realities depicting champions in a different light. There are still skins that are lore related of course, but then there are skins that don't fit with the new universe. Blood Moon went from Akali and Shen performing a play about demons, to including Ionian versions of the Shadow Isles, to now becoming a blood cult. Pentakill doesn't work in the main world, so I imagine that they're some band in a different world. Maybe they go open shows for Popstar Ahri?

That leaves with questions about Tango Eve and TF, along with Sinful Succulence Morgana. I think an easy explanation for Morgana is that she wants to be a part of Tahm Kench's crew, but her cooking is bad. That, or she's trying to start her own business, but again, bad cooking.
