Until now you didn't have the capability to do it. It's being given to you, paid, on a silver platter. I would personally take it, or otherwise stash it in an increasing bucket list of things that probably won't ever end up being realized. A lot of dreams are lost to inaction. I read that luck is nothing more than taking opportunities. This sounds like one. The main thing would be to make sure your wants and needs are on a legal signed paper, so that even if you leave the company, you are a major part of this particular project and it's success even after you are gone, or at least compensated in an appropriate way should you choose to move on or whatever may happen. You referred to it as a separate division, so it would seem to be doable in a way that protects your intellectual property and input.
