I want to make diving suits in Minecraft

I'd like to... well, make a diving suit out of copper, opaque glass, and a water-breathing potion. What it would do is allow you to walk on water, and with this mechanic, you'd float to the surface if you drowned, but with this suit, you could survive. The opaque glass would prevent drowning people from seeing you, but you could still see them. To create it, you'd apply the diver template to all the armor except the helmet. For the helmet, you'd put opaque glass in the center, copper around it, and replace the copper above the opaque glass in the crafting table with a lightning bolt. For the oxygen tanks, you'd place a water-breathing potion scattered in the center and cover it with copper. Oh, and it would rust, slowing you down, so you could add the honey suit, and you're good to go. It's just my idea; I hope it gets votes and that Mojang sees it. Thanks.
