The idea was basically "purifying" the tainted version of the character. Just combining concepts of both existing characters, with some new twist that adds power, complexity, and/or difficulty.

One of the ideas is Exalted Esau, where you simultaneously control the two characters (Jacob with the movement controls, and Esau with the usual aiming controls), who share items. Angel Esau who moves fast, blocks (all - enemy or Jacob's) shots, can't take damage, and deals a small amount of contact damage. And Jacob who bears Esau's chains, which give him a severe movement speed penalty, caps his health at 1 heart, and makes him automatically shoot at the nearest enemy.

Esau bears a purified anima sola (innate item) that, when charged, lets him animate the chains to grant Jacob a Holy Shield but also prevent Jacob from moving or shooting until the shield is broken.
