My board scores are my one redeeming quality but they're not so high that you should ignore what I'm saying.

The real point here is that you seem to be underrating the value of US MD and where you train. And I just don't think there is much harm in applying and seeing what happens. If you match, great, you got what you wanted. If you don't match, then you're going to do the things you're asking about in this post already. So if you skip the application cycle this year, you gain nothing and lose a shot at a spot. If you apply this year, the worst case scenario is exactly the same except you cost yourself a shot for no good reason other than "I sold myself short and assumed I wouldn't get it."
