Yes (Subjective).
First, lets look at "gloves" that are directly related to Monks:
Ki Straps (p. 113, Magic Item Compendium)
This will add "passive" enhancement bonus, such as +2 to the DC of your Stunning Fist attack.
The crafting requirements are:
Prerequisites: Craft Wondrous Item, Stunning Fist, magic weapon.
Now lets look at a common glove:
This metal glove lets you deal lethal damage rather than nonlethal damage with unarmed strikes. A strike with a gauntlet is otherwise considered an unarmed attack.
Let's look again at the [Monk's Unarmed Strike][3]:
A monk also deals more damage with her unarmed strikes than a normal person would, as shown on Table: The Monk. The unarmed damage on Table: The Monk is for Medium monks.
There are a multitude of magically enhanced gauntlets in the Magic Item Compendium that add damage in some fashion, and even store charges to do verious things.
Throwing it all together
Could Ki Straps be enchanted? Yes. They are obviously a masterwork item, that required Craft Wondrous Item, requires Magic Weapon cast on them, and offers an enhancement bonus to your Stunning Fist attack.
If it can have one enhancement, there are no rules stating it can't have another enhancement bonus.
Regarding information from "Gauntlets & Spiked Gauntlets: How do they work?Gauntlets & Spiked Gauntlets: How do they work?" there is no real reason why you can't enhance the gauntlets (as it is a glove), as a weapon, and it still treated as your Monk's Unarmed Strike.
