Its a good idea, I would offer the following advice:
Do it for yourself as much as you are doing it for the ER. Do it to learn about putting together collaborative projects, to search the literature on topics that you enjoy or feel need to learn more about, to get the experience of publishing, editing, and working with the non-clinicians involved.
Many of us deal with ER personnel who seem to have minimal ortho knowledge or interest. I would argue the vast majority are not like that for lack of available resources. No matter how well you spoon feed them, I don't think you can change their behavior.
Some just like telling you what to do. Some are lazy except for when it comes to making excuses. They'll have all kinds of concerns about their liability if you do not see people. Every annoying ER patient suddenly has compartment syndrome and needs to be seen by ortho at change of shift.
I'm not saying I disagree with your idea, I would just suggest that you consider a success to be a well put together project that you get a lot of knowledge and enjoyment out of. As it sounds like you already know, those two things are rarely ever associated with the emergency department for us.
Good luck.
