2 tower shields would let you...set up cover in a direction while you retain the +4 AC bonus from the other shield. Not exactly ideal, especially since shield bonus won't stack with other shield bonus.
Since tower shields can't be used to shield bash (for good reason) you wouldn't have any kind of offense. Why would anything pay attention to you? Any intelligent monster would just ignore you.
Also the gauntlets you're describing would be the size of a light shield. A heavy shield should cover your body from slightly above the shoulder to your thighs so its easy to move it a little to protect your head or feat. Tower shields normally are the height of the person wielding it and wider than the wielder so they can easily hide behind it.
If you wanted to tinker something you might consider some sort of portable barrier that you could quickly set up to provide cover for others. Watch a Rainbow 6 Siege video or two to get an idea of what I mean. Imagine one of the wall reinforcing devices, without using it to reinforce a wall. Or more to make a portable wall that you could set up anywhere.
Just make sure you have some sort of offense. Like maybe an engineering tool that doubles as a war hammer?
Oh the Tower shield character is different from the gauntlet character, my bad I should have clarified, although I like the idea you gave. It seems to me that the dual tower shield character isn't happening, but the gauntlet character could have his gauntlets (or at least one), they still serve as actual gauntlets for the purpose of combat but maybe make the plating on the back of the hand extendable/retractable or just longer to work as a heavy shield, or add a long blade to the pinky side of the hand to work kind of like built-in bladed tonfa.
