it has already been done. So, would Michael and Issa be able to sense what the other is? Or perhaps already know they are of the same species?

I would believe so. I think it would be wise to borrow an element from a book I read where wizards and witches can sense each other's magic through their auras. The color of the aura can vary and only wizards and witches can see it. For example on the color, it can be based off your favorite color or off your main magic abilities.
