Moonblade as primary weapon

[CryptbornAkryea]

Let's say a friendly artificer used a moonblade spell to create, well, I guess a moonsabre?

How would it work in respect to light/one-handed rules?
What about enchanting it? ie adding +1enhancements and the like

According to the spell description, "if you are proficient with any type of sword, you can wield the beam as if it were any type of sword and thus gain the benefits of any special sword skill you might have, such as Weapon Focus." By my reading, that means if you choose to wield it as a type of sword that is a light weapon (e.g., a short sword(, the Moon Blade will gain those benefits.

However, it's still not an item, it's a spell effect. I don't see any reason to think it can be enchanted.
