I don't think it's possible to remove and then put the shadow again... Well, I've never seen such an action anyways. What you can do is what Ryushi said, duplicate that unit and in the copy just remove the shadow, then change between, if it's a hero, just set values of the level, and ability levels, and voila.
I dont know for sure but maybe you could add the ghost ability to the unit. since it makes the unit invisible maybe it removes shadow, but then again im just shooting out ideas
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
