Kasatha Titan Mauler Unchained Barbarian with 4 Meteor Hammers

[s00pahFr0g]

Could a Kasatha Titan Mauler with the multi weapon fighting feat wield a Meteor Hammer in each hand as a double weapon thus granting 8 attacks?

Follow up question, could the same character have 1 meteor hammer in fortress mode for the +1 AC and reach and the other 3 meteor mode for 7 attacks?

Double weapons require two hands to be used as double weapons. Holding them in one hand turns them into one-handed weapons.

So the jotungrip class feature wouldn't allow you to wield them 1 handed as a two handed weapon?

[Dragonborn3]

Not in a way that gets you eight attacks.
