Song is "Pump it up" by Endor
The fanfic that inspired this idea is "The New God of the Forge" by ahmadnazem while i was listening to this song thinking of Rin taking over Ishtar/Ereshkigal, Taiga takes Jaguar warrior, Luvia takes Astrea, Saber takes Rhongmyniad(?), Sakura takes Parvati, and Archer Takes over Shiva and they happen to meet up at something like a mythology mass gathering event.
Here is the idea:
Imagine at this gathering you see the girls gather together to talk about whats going on in their lives and how Archer is Shiva and Shirou is Hephaestus all the while Shirou and Archer are laminating their lives and decide to get drunk together and next thing you know is some musical gods are playing party music and the girls look over to see a drunk Archer and Shirou walking/dancing with a large jug of divine wine in hand hanging out rather than hate each other.
