No, it's not possible! You can link the children to other parents, and then delete the parents, but you are not allowed to have orphants, it's illegal "by definition".

Now, do I have to post this same message a number of more times, in the other identicals thread you have created?

One question = one thread. One thread with more questions is OK if the questions are closely related, but one question posted several times in different threads is against the rules.
