You could.

Given a few days it will dry out and shouldn't give you any trouble. You can also pour it out in a extra tub for a couple days before using it if you want it dried a bit before you use it. I keep a good amount on hand and many times it is dry by the time I need to use it so I pour water in it and stir it up before using it.

In a few of my cages I use a mixture of the Forest Floor, Eco Earth, and Repti Bark. There is no reason you could not mix it with what ever substrate makes you happy.
