JQuery wraps multiple elements regardless of level

This is my first stackoverflow post. Until now, I could always find the answer here, but this time I could not.

Here is my DOM structure:

<div id="elementA">
    <div id="elementB"></div>
    <div id="elementC">
         <div id="elementD"></div>
    </div>
    <div id="elementE"></div>
</div>

How can I wrap 2 or more selected “random” items in a wrapper container? This should also work if the selected items are on a different level and if there are other items in between. The DOM structure of all other elements should not be affected.

Following a few examples:

Example 1:

I was thinking of something like this:

var element1 = $('#elementB');
var element2 = $('#elementE');

??? $(element1, element2).myWrap(".wrapper"); ???

The result should look like this:

<div id="elementA">
    <div class="wrapper">
        <div id="elementB"></div>    
        <div id="elementC">
             <div id="elementD"></div>
        </div>
        <div id="elementE"></div>
    </div>
</div>

2 Example:

Elements are on different levels.

var element1 = $('#elementD');
var element2 = $('#elementE');

??? $(element1, element2).myWrap(".wrapper"); ???

Result:

<div id="elementA">
    <div id="elementB"></div>
    <div class="wrapper">
        <div id="elementC">
             <div id="elementD"></div>
        </div>
        <div id="elementE"></div>
    </div>
</div>

Example 3: more than 2 elements:

var element1 = $('#elementD');
var element2 = $('#elementC');
var element3 = $('#elementA');

??? $(element1, element2, element3).myWrap(".wrapper"); ???

<div class="wrapper">
    <div id="elementA">
        <div id="elementB"></div>    
        <div id="elementC">
             <div id="elementD"></div>
        </div>
        <div id="elementE"></div>
    </div>
</div>

Example 4: different trees:

var element1 = $('#elementD');
var element2 = $('#elementF');

??? $(element1, element2).myWrap(".wrapper"); ???


<div id="elementA">
    <div id="elementB"></div>    
    <div class="wrapper">
        <div id="elementC">
             <div id="elementD"></div>
        </div>
        <div id="elementE">
             <div id="elementF"></div>
        </div>
    </div>
</div>

jQuery.fn.myWrap = function(options) {

    var $mostNested = null;

    // find common parent
    var found = false;
    $parent = $mostNested.parent();
    while($parent != null && !found) {
        if ($parent.find(e).length == e.length) {
            // Right Level
            found = true;
            var toWrap = [];
            var numDirect = 0;
            $.each($parent.children(), function(i, item) {
                var direct = $(e).index(item) >= 0;
                var sibling = $(item).find(e).length > 0;
                if (direct) numDirect++;
                if (direct || sibling) toWrap.push(item);
            })
            if (numDirect == e.length) {
                // All direct! (Example 1)
                $parent.children().wrapAll("<div class='wrapper'></div>");
            } else {
                // Other Examples
                $(toWrap).wrapAll("<div class='wrapper'></div>");
            }
        }
        $parent = $parent.parent();    
    }
};


$(document).ready(function() {
    // Example 1
    $('#elementB, #elementE').myWrap();
    // Example 2
    //$('#elementD, #elementE').myWrap();
    // Example 3
    //$('#elementD, #elementC, #elementA').myWrap();
    // Example 4
    //$('#elementD, #elementF').myWrap();
})
