There's quite a variety of styles just located in stat builds + weapon use that makes this pretty impractical.
Finesse + two-handed = Spear
Finesse + One-handed/dual-wielding = Dagger(s)
Finesse + Ranged = Bow/Crossbow
Intelligence + One-handed/dual-wielding = Wands
Intelligence + two-handed = staff
Strength + one-handed/dual-wielding = one-handed weapons
Strength + two-handed = two-handed weapons
And that's just off the top of my head. So already it's impossible to experience every configuration, because each one-handed represents weapon+shield, weapon+weapon, and weapon+nothing, so that's 13 different ways to wield a weapon and max out the stat, and that's saying nothing of builds where you go even further and mix/match.
Now, if you're just talking about using skills, it IS possible to take advantage of all the skills. A dagger user can take advantage of everything in scoundrel and warfare, though warfare better serves the two-hander user, etc. An intelligence character can make use of every spell, as they scale off intelligence.
Essentially, what I'd suggest instead is you find what works for yourself. Instead of trying to do everything in one playthrough, do what seems best in your first playthrough, then try something different and see how that works instead. I've beaten the game 3 times now and each time my party had a different composition and general tactic, and each had their own advantages.
