You know, you don't want to reinvent the wheel, but you can't worry about what other folks have done, or haven't done. If you tell someone you are pursuing some project, or mission, the first thing you usually get in response is that it can't be done, or it has been already been done, or, you know, why the fuck bother?
Yes. The naysayers are legion. Best to tune them out. Maybe pretend that what you taking on is something that has never been done. You do it and, you know, you see what the fuck happens. Damn the torpedos.
