I'm by no means any kind of an expert, especially with a kiln, but I don't know why it would be any different than air drying. Same thing just a shorter period of time with a kiln.
That being said when I had all them trees cut a few years back I was air drying maple, cherry, oak and box elder at the same time in the same stack. I didn't have them mixed, but all part of the same stack.
My $1.398 worth of wisdom.
