Just use mods like "double monster spawn" Monster madness" and "tougher bosses" with an xp-reduced and monster-levelup mod to balance the game, so instead of have fights 4 vs 6 as usual you have fights 6 vs 12 and you will be fine (The mods are all compatible because they are made by the same guy). I am playing that now and it is working fine so far, even in nameless isle.
You cannot see all stories in one playthrough though, because the plot of the characters may change if you are playing an origin avatar ( Companions stories are more or less fixed, but if you are an origin avatar you can make different decisions that can change some things, at least in Sebille and Ifan. Not much in Beast... man, the guy is hopeless no matter what)
