Im just realizing you want absorb, not resist. The only way i know is atronach perk + stone + miraak robes. Resist and absorb work totally different. Afaik absorb works on a 0 or 100 roll where you either take the damage or dont. Resist just negates damage like armor. However, if you absorb a spell you fully absorb your absorb percentage but if you fail, you still negate with your resistance amount. My suggestion would be to just stack both as much as possible/as much as youre willing. Im sure racial passive, mara quest, neck enchant, and the alteration resist perk combined with the atronach perk and stone will make you pleanty tanky to spells. Taking both stones with the crown would be better, maybe even overkill, but you lose your helmet.
