Here's what I think:
 * I think Dissidium, being a "true" hybrid champion, could really benefit from constantly blending in casts and autoattacks. Rather than being a pure caster (or autoattacker), he could be a "weaver", and so his spells should encourage him to autoattack somewhat.
 * To fit in with the theme of the claw, I think Ghostly Claw, instead of slowing enemies, could apply a debuff to enemies that would cause Dissidium's basic attack to make them bleed for magic damage. I was also thinking you could give it its own attack pattern by having it damage enemies in an arced line (so anyone in front of or behind the arc wouldn't take damage, just the ones in the middle), to distinguish it from other conic skillshots.
 * Just a minor change, but Siphoning Breath's healing would do better if it scaled as a percentage of the damage it deals, since it would then also benefit from Fatal Wounds (Dissidium would heal more the lower on health his target is).
 * Energy champions typically have a way of restoring energy through abilities. This could be the function of his W: Spectral Grasp could be an AoE that restores Blue Shadow Energy for every enemy champion hit, and Shadow Step could allow Dissidium's next few autoattacks to restore Red Shadow Energy. Similarly, to add more gameplay to Dissidium's energy management, instead of giving his resource lots of passive effects, you could allow Dissidium's to restore Red energy through spellcasts in Wraith form and Blue energy through basic attacks in Predator form by an amount dependent on his ultimate.
 * From this you could move the root away from Spectral Grasp (I'll explain below) and turn Shadow Step into a blink. Instead of having it grant untargetability, you could have it grant unit walking for a duration (to fit better with the predator theme).
 * I think you're right that Curse of the Grave could do with mixed damage. How about this: Dissidium marks a target for magic damage, and damaging the target with an ability would root them and cause them to deal physical damage to nearby targets, itself included.
 * Having Dissidium's next autoattack deal magic damage would be the perfect bonus to Shadow Blend. You don't need to add bonus physical damage to the next spellcast either.
 * I was thinking of moving some effects around for Soul Swap: in addition to restoring energy upon every kill and assist, and through the above variable effects, you could move Ghostly Claw's slow to Dissidium's next basic attack and have him deal physical damage and knock enemies back upon entering Wraith Form. All of these bonuses would be worth upgrading.
 * As a side note, ranged champions and, by extension, champions with a ranged form, don't gain magic resistance per level. I don't think you need to give Dissidium any as a special case either, since he's meant to be fragile as both a mage and an assassin.

To be clearer, here's the updated kit I propose:

Dissidium still has 100 Blue Shadow Energy and 100 Red Shadow Energy, and both regenerate at a rate of 5 Shadow Energy per second.
