Legend
A remake of the War of the Lance adventure path - drawing on the originals but not in thrall to them, and removing the Heroes of the Lance entirely (the PCs take their place).
Something like this. Inspiration not an update. I would put a sidebar something like "infinities" where the PCs can replace the Heroes of the Lance but doing so creates a new timeline or something.
Otherwise the WotL is the backdrop.
