Posting comments to a different post/page. (Fake the comment_post_ID)

I am trying to post comments to a different page from the one I am posting the comment on.

i.e. I am posting a comment on page 2, but want it show up in the comments loop only on page 23.

I found this in the HTML of page 2
<input id="comment_post_ID" type="hidden" value="2" name="comment_post_ID">and figured if I changed that value=”2″ to value=”23″ then it would just post the comment to page 23.

I’ve had limited success, I can post to page 19, and page 24, but all the rest I just end up on a blank wp-comments-post.php page.

Thank you for any help, much appreciated.
