Can I dual wield two-handed weapons in D&D 5E?

I’ve been looking into this for awhile now. I have a level 4 Dragonborn Paladin with the Dual Wielder Feat. I currently have two warhammers, but I’d like to use two mauls for the extra dice. After all, 4d6 is better than 2d8. If this isn’t something that would work, that’s fine, but it’d really be nice.
