A little idea for Blake's semblance

There have been other posts and discussions about how the character's semblances would evolve, or just a creative way to use them; but I was always at a loss on what to do with Blake.

I think I have a very simple, maybe even obvious solution to get a little bit more out of it: simply have Blake be able to make shadow clones of other people and objects. Imagine if you will, Weiss and Blake are in danger and need to get the hell out of dodge, Blake grabs Weiss and runs, leaving behind a copy of herself and Weiss. Lets take it a little further, team RWBY are on an airship fleeing from...hell I dunno maybe the Empire is after them, but Blake grabs onto the interior of the ship and concentrates, Yang dives the ship into a canyon while the shadow decoy ship leads the enemy away. Lets go even further, what if she doesn't even need to touch someone to make a shadow clone of them? Here's a scenario: There's a civilian family about to be torn apart by Grimm, Blake is running toward them, but is too far away to do anything yet. She tells the family to run and they do, leaving behind shadow decoys.

Now it's been a while since I saw any of the older RWBY stuff, so you guys might be like: "what'r you talkin' about? Blake's always been able to do that." But still I think I'm on to something, what do you guys think? Do you like the idea? Do you hate it? Any other ideas on what to do with Blake's shadow-clone semblance?
