Superior Unarmed Strike + Gauntlets?

[Townopolis]

When gauntlets say "otherwise considered an unarmed strike" this means that anything you use to modify your unarmed strikes will modify your gauntlet attacks, yes?

This means you can use gauntlets in conjunction with superior unarmed strike to up their damage, and, if I am correct, would allow you to stack an amulet of mighty fists with two magic gauntlets (enchanted per the normal rules for magic items) to get +5 enhancement bonus to both and as much as +9 in equivalent bonuses

e.g.

Wearing an amulet of mighty fists +5 and two +1 acidic, shocking, flaming, frost, wounding, metalline, sacred gauntlets (using TWF). The amulet supersedes the enhancement bonus of the gauntlets.

or does it not work that way?

Yes, it works that way, but it's terribly inefficient. Greater Magic Weapon is much, much cheaper.

You're still not treated as being armed, so you'll provoke AoOs every time you hit someone with those, no matter how good they are.

thus taking Imp. Unarmed Strike, which is required for Superior Unarmed Strike anyways (SUS to up the damage dice). Although I'm sure SUS is only marginally better than weapon spec.

[Edit] Actually, at level 20, IUS and SUS are roughly equivalent to bastard sword proficiency and OTWF if you want to dual wield them, so definitely not what you'd call an optimal decision.
