LessWrong/Alignment forum essentially has this for users with >100 karma. If you have a draft you can click on the feedback button and ask for this kind of feedback.
That LW post review interface is a thin veneer, just making pre-publication feedback a tiny bit more convenient for some people (unless they already use Google Docs, Notion, or other systems to draft their posts which offer exactly the same interface).
However, this is not a proper, scientific peer review system that fosters better research collaboration and accumulation of knowledge. I wrote about this recently here.
