Moreover, if you check the wiki about armors, it says about lava armor. that would be great. Can you try to create a mod that will support this?
That would be cool! But what block would be used to make it? I'm guessing blaze rod over an obsidian plate, that would be a nice extension to this mod. Making the lava armour flowing will be tough, I don't think minecraft will take .gif's either. I could try.
I think it is with lava buckets.. You can check it out. This only, if you make it, I probably would test it, to see if just the armor can kill the zombies with transfer of lava..
