There's nothing extra in a 192kHz signal that would help with the vinyl mastering process. You could make a technical argument for the benefits of a 24-bit source, but in practice even those benefits would be utterly swamped by the SNR of vinyl.
And you might even have a point, as long as you acknowledge that “remastering for vinyl” doesn’t actually necessitate distributing on vinyl, and what you describe as “the sound of modern CD audio” is entirely the fault of human decisions and not the CD format itself.
Also, you’d need to acknowledge that your description of what “sounds better” is a subjective assessment. It is fair to say that vinyl sounds better to you if what you like is that RIAA processed, variable noise floor sound.
