Is it possible to remove the main rich Text box editor?

I am using the simple fields plugin to provide additional rich text editors and have no need for this ‘main’ text editor box on any of my ‘page’s

I have tried the following code in my functions.php:

function my_remove_meta_boxes() {
remove_meta_box('postdivrich','page','normal');
}
add_action( 'admin_menu', 'my_remove_meta_boxes' );

Apparently this will not work since it is not actually a meta box…

I suppose I could sneak some jQuery in somewhere: ('#postdivrich').hide() but I am not really sure where to put it, and suspect that there is a better way.

Any help would be greatly appreciated

Edit: this question describes how to do what I want, but for a custom post type. Can I apply this same technique to ‘pages’ somehow?

Edit 2: Using noob power I made something work, but for all post-types and with it flashing on screen before being hidden. I skipped JQuery and went straight for plain ole JS:

//REMOVE MAIN TEXT CONTENT BOX FOR PAGES
function removeMainTxtContent(){
    echo '<script>window.onload=function(){document.getElementById("postdivrich").style.display="none";}</script>';
}add_action('admin_head', 'removeMainTxtContent');
