Rework the Body Shield LVL 4 perk to function similar to Octane's health regen, but with armor instead.

I don't see how the shield would be op.

You look at golden helmet and see half cd ult/tactical ability; you see golden back and see near instant shield replenishment during combat (provided you have the items necessary). Golden body shield currently is extremely underwhelming because who has the time to set themselves open for 5-6 seconds.

If you put 10 seconds delay after last damage taken and make it 1 point of shield per 3 seconds, that'd still take 5 minutes to refill all shields. Who would want to roam for 5 minutes without full shields? One Kraber headshot and you are gone. You wander into an enemy squad without full shields? You are asking for trouble.

I had some ideas myself that'd be strong but still not as strong as 5s phoenix kit / 2.5s battery.

Smokescreen - when your body shields depletes, you instantly create a smokescreen (like Bangalore's smoke) that covers you. Put a cooldown on it - like 60s.
Unstoppable - as long as you have body shield, you cannot be slowed by enemy shots / ultimate / grenades. (kinda like Octane's adrenaline rush)
