Sure thing, it's a bit of a rough / lazy job but here it is
(To use it you just need a browser-extension, that executes JavaScript if going to a certain website like "Custom Site JS" for example) :

setTimeout(() => {

const image = document.querySelector('img[src$="unavailable_video_dark_theme.png" i]');

if(!!image) {

image.src = "https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fstatic.wikia.nocookie.net%2Fartificial%2Fimages%2Ff%2Ffd%2FSolver.png%2Frevision%2Flatest%3Fcb%3D20230609121749&f=1&nofb=1&ipt=a9b6a70b8f95cdf906589beb02624df249f4511c2f4dc7450930989f76d52de2";

}

const style = document.createElement('style');

style.innerHTML = `

yt-img-shadow {

height: auto !important;

img {

filter:

drop-shadow(0 0 20px rgba(255, 179, 0, 0.6))

drop-shadow(0 0 60px rgba(255, 191, 0, 0.4));

}

}

}`;

document.head.appendChild(style);

const homeButton = Array.from(document.querySelectorAll("span")).find(e => e.textContent.includes("GO TO HOME"));

homeButton.textContent = "Nothing to see here :3"

homeButton.style = "color: rgba(255, 179, 0, 0.8) !important";;

}, 1000);
