Post Game Modding Suggestion
The Slightly More Simple Part
Now the post game is seemingly just plopping you down in the pre-final-battle worldstate, I'd love to see a mod which makes it just after Nilfgaard has left and with the Temerians/Redanians now in control of places like White Orchard, replacing the Nilfgaardian guards with the nation which now owns Temeria would be a great immersion piece, places like Novigrad might be a larger undertaking however, so while all the assets are already there it'd still be a lot of work changing banners, guards and such to fit the ending of the game the player gets, but I feel that it will improve the post-game free roaming vastly.
As another little thematic change there could be efforts being made to clean up battlefields and small quests to guard said people from Ghoul's and such + more contracts.
Much more Ambitious ideas
A change like this + some post game interaction with Ciri, Yen and Triss would make the post game much more entertaining, set during Ciri's Witcher training with Geralt on the path, it'd be nice - But that's more of an expansion deal than a mod piece.
Either that or an expansion/mod with a very good Ciri impersonator to allow you to free roam as Ciri and do contracts with Witcher equipment unlocked such as bombs her own crossbow, inventory - Some form of upgrade system for Zireael and adding armor to her clothes like how the Witcher schools gear improves and some form of new potion system seeing as she cannot use Witchers potions would be AMAZING.
