I have never come across anything like that. As per my knowledge ,the only way I see would be via a PhD via publication. And that would require getting academic articles published in reviewed journals around a theme.
And then, working with a university which does a PhD by publication to credit you for it!
Thats not a very easy job to do if you are not very good at what you are doing. And actually might take more time than the time it needs to do masters. :/
I would suggest you to do masters first and then head towards your goal.
