dude, with 215/240, good recs and a strong intern year, you totally have a shot. the issue is not as much is it possible, but how to do it without burning bridges in both directions.
you do not want to burn your home program (assuming that's where you match.) you want them to say "gee, we think you're great. but, if you don't want to do what we have spent our lives doing, we will help you get into your new specialty." one way to get help is to make sure your elective months help you meet ortho intern req's.
also, with regard to ortho, no one wants an intern who's gonna leave. you are deciding this without even matching yet. i am not saying i don't understand (cuz i totally do) but 1) if ortho's so great why didn't you go for it before (i know you answered that, but i'm devils advocate here) and 2) are you sure you aren't just having a totally understandable case of buyer's remorse after choosing a specialty?
long post, sorry. i can just imagine how stressful this must be for you. good luck
cheers.
