You have a right to do what you want... I have never complained when people create the same thread as mine. You can see in this thread, me asking binominal to create a new thread with new options, after he asked me to update the poll (which the system doesn't allow you to do) and I would ask mods to lock this thread. He didn't create the new post, so I did.
I am 100% happy to ask mods to lock my 2.0 thread for yours, I wasn't that happy as I left out one very credible name, Xabi.
