the inner members of kara can probably change there chakra signatures

Still some leaps there I wouldn't personally make. I think it's too soon to assume there's more than one alien group interested in the ninja world at this point, or assume that they've ended up here and yet flew under the radar like Kara has. Further, we don't have any evidence or indicator that Kara's inner members have the ability to alter their chakra signature, an ability that's largely limited to the likes of Zetsu and those with duplication techniques.
