Interested in research, not in coursework
You would certainly be an exceptional case. Some would interpret that as a difficult case. When you don't fit the expected mold it is harder to evaluate you. That doesn't mean that you are at a disadvantage, necessarily, but you would be at some places that aren't very flexible. 

I think that a research focus at the MS level is more typical in Europe than in the US, however, so you might consider location as you look for a position. In some fields in the US research is also dominant, of course. 

But even in the US, if you can make contact with a professor or two at the graduate level who might be willing to give you a close look, you might be fine. However, many programs have fairly strict rules about things. You might, be able to do independent study to cover many of them, but that can be intensive for the faculty, so don't expect too many concessions unless you are exceptional in the positive sense as well. 

Your real problem, however, is that if you don't follow the "accepted" course of study you are liable to miss some things that it is valuable to know. The advantage of coursework is that someone has seen the bigger picture and has selected topics that are useful and given thought to how you can develop skill in those areas. Missing that can be a long term disadvantage, so tread carefully and seek advice on your personal academic journey.
