Interesting idea for Gibby gun shield

Hmm make the gun shield absorb a portion of damage instead of having hp on its own and thus making it indestructible so the way this works is lets say gibby absorb x amount of damage from attacks with his gun shield equal to the total percentage of his hp so that he can only absorb 50 dmg from each attacker without destroying the gun shield (stacks with fortified). The main point of this is that it would be possible to use the gun shield even after several assaults from different attackers because the gun shield cant be destroyed in this scenario. You can go further and make things interesting by making damage dealt by gibby recharges his gun shield so that it start from zero and absorb damage in its full capacity. Just an idea to make him more fun and interesting.
