Berserk: To represent the armour's ability to take control of the host's body when his brain is damaged, manifest control body on yourself when your hp is low, making your psicrystal the point of origin. This works best in games where the negative hitpoints range has been houseruled larger.

Gravity Implosion: Transcend Limits + Twinned Empowered Psionic Disintegrate (expend focuses of both psicrystals)

Astral seed just fits awesomely. Another trick would be to have the character perform a true mind switch with their psicrystal so that if that shiny thing on their forehead is destroyed the body dissolves (this would also remove the need for psionic fly, since the psicrystal-body can fly by itself).

EDIT: If you can use psychic reformation to add additional powers, you have room to take Azure Toughness, Troll-Blooded and Tireless to better represent the Guyver's regeneration.
