In a word: No.

In more words: No, I can't say that about Toph & metalbending, because as you so helpfully pointed out, she taught people, unrelated to her, how to do it. This hasn't happened for bloodbending without a full moon, even after people now know that it's theoretically possible.

According to your overly saccharine argument about practice, this should not be true. Hama should have been able to do it. The Bloodbending criminals after Yakone should have been able to do it.

But they weren't.

Because they don't have the genetic predisposition for it.

And no matter how much they try, they will never be able to do it.

It's like Waterbending itself. Just because you've inherited it, it doesn't mean that you don't have to train it. However, the inverse is not true--if you have not inherited it, then no matter how much you train, you can't do it.
