A No-Border Full Black Theme for SMPlayer?

[TIWSM]

I'm thinking of Basic GUI only in black and without the freaking borders. I use SMPlayer as my main video player on almost every device I own, and frankly getting it look decent is easy with the Monochrome icon set and Basic GUI, but the real pain are the borders, coupled with the forced light theme. I'd be for anything with any of those removed, both preferably. My concept linked below:
