New Block Idea: Hull Polarization (vanilla shield mod)

In Star Trek: Enterprise they could polarize their hull which would make the metal hull stronger and more resistant to certain physical damage due to the electrical charge. (if your wondering there are some polymers and alloys in real life that can be changed with an electrical charge so this is viable) I think it would be great to have this as a special block called the "Polarizer" that is designed to us a large amount of electricity to create a protective over-shield (this overshield adds 1/3 of the ships total armor health on top of the original armor health), the Polarizer prevents armor and other certain exterior blocks from getting damaged until the over-shield health is depleted. Once the Polarizer shield is down it would disable the polarizer block, you would have to go and repair it by adding a few more computer chips until the block is functional again(since it requires a lot of energy to work I would assume destroying it would cause a massive short inside so replacing the computer chips makes sense). I think this would work well by just changing/increasing the health values of certain blocks like armor,conveyors,turrets and other commonly used exterior blocks when the "polarizer" is turned on (also making them immune to damage warping). after the added health is gone the specifically protected blocks would become vulnerable again.
