Moving ModalPopup Outside the IFrame. Possible?

/* function in the main(parent) page */
var _onMyModalPopupHide = null;
function pageLoad(){
    // would be called by ScriptManager when page loads
    // add the callback that will be called when the modalpopup is closed
    $find('MyModalPopupBehaviorID').add_hidden(onMyModalPopupHide);
}
// will be invoked from the iframe to show the popup
function ShowMyModalPopup(callback) {
    _onMyModalPopupHide = callback;
    $find('MyModalPopupBehaviorID').show();
}
/* this function would be called when the modal popup is closed */
function onMyModalPopupHide(){
    if (typeof(_onMyModalPopupHide) === "function") {
        // fire the callback function
        _onMyModalPopupHide.call(this);
    }
}

/* functions in the page loaded in the iframe */
function ShowPopup(){
    if(typeof(window.parent.ShowMyModalPopup) === "function") {
        window.parent.ShowMyModalPopup.apply(this, [OnPopupClosed]);
    }
}
// will be invoked from the parent page .. after the popup is closed
function OnPopupClosed(){
    // do something after the modal popup is closed
}
