TES, the setting is piss easy to adapt and if anything has the FF problem of having well more than one full set's worth of relevant characters and events to the point where they could easily double up on it like they're doing with Tolkien, even if they give TESO the Korra treatment (they should)
The guilds basically stat themselves, you've got B Dark Brotherhood, WB Morag Tong, UB Telvanni and Thieves Guild, BR Mythic Dawn, R Fighters Guild, RG Companions, B College, WB Mages Guild, and so on
Fingers of the Mountain as an overcosted burn spell
Plenty of equipment that's easy to work with, both basic shit like Umbra and Goldbrand and gimmickier stuff like the Mask of the Gray Fox phasing something and making a token copy of it
Yagrum Bagarn, probably with blink support
Rakdos Cicero please god I want more clowns
The Princes as Theros-style gods, probably with Sheo flipping into Jyggalag and Azura as Divining Top with a body
Warp in the West as an annoying Sway/Thieves' Auction card
The Last Dragonborn as the obligatory 5c commanderbait (alternatively Tiber Septim)
Three precons named Sons of Skyrim, Jaws of Oblivion, and Moon and Star
I can't for the life of me think of a decent effect for Dagoth Ur/Kagrenac's tools/Heart of Lorkhan/Numidium though
