Does the Dual Wielder feat work with the Armorer’s Thunder Gauntlets?

Can you do this to do bonus action attacks as an armorer?

The Dual Wielder feat grants the following:

You gain a +1 bonus to AC while you are wielding a separate melee weapon in each hand.

You can use two-weapon fighting even when the one handed melee weapons you are wielding aren’t light.

The Thunder Gauntlets are described as follows:

Each of the armor’s gauntlets counts as a simple melee weapon while you aren’t holding anything in it, and it deals 1d8 thunder damage on a hit.
