Hi!
I wrote my own userscript (Convert Youtube Embeds to Image Links) based on this script, and added some crucial features you might like to add to your own. Mainly it adds support for dynamically injected videos after pageload. All the other stuff isn't needed for a pure text-link, so you can disregard all that. The important stuff is in the MutationObserver, but I also rewrote the majority of the code.
Make use of it, or not, it's up to you. But now you know :-)
