If you're a Titan's Fist and get Transpose Soul, you can specifically look for her abilities and Soul Armor into something physically resistant.
Fair warning though, Madevra has Heroic bonuses which make her hit harder and take less damage, so even if you perfectly copy her stats, you won't be as much of a juggernaut.
Still, you can give it a good go by using multi-hit attacks and Guilt for the same sort of melee endurance.
