Data binding between 2 sibling elements

Question

Is it possible to pass the bindings from one child to the other child in the parent? The parent doesn't need to use the bindings. It will need to be 2 way.

To put it another way, I need to siblings to share data-bindings.

   <app-drawer id="drawer">                                                                                                                                                                                  
     <div class='left-bar-container'>                                                                                                                                                                                        
     <listings-drawer></listings-drawer>

           <!-- Main content -->
    <iron-pages
        selected="[[page]]"
        attr-for-selected="name"
        fallback-selection="view404"
        role="main">
      <my-view1 name="my-view1" form-loading="{{isLoading}}"
        pic="{{pics}}" area-code="{{areaCode}}"></my-view1>

I need <listings-drawer></listings-drawer> to have access to form-loading="{{isLoading}}", pic="{{pics}}", and area-code="{{areaCode}}"

<app-drawer id="drawer">                                                                                                                                                                                  
 <div class='left-bar-container'>                                                                                                                                                                                        
 <listings-drawer loading="{{isLoading}}"
    some-pics="{{pics}}" some-area-code="{{areaCode}}"></listings-drawer>
       <!-- Main content -->
<iron-pages
    selected="[[page]]"
    attr-for-selected="name"
    fallback-selection="view404"
    role="main">
  <my-view1 name="my-view1" form-loading="{{isLoading}}"
    pic="{{pics}}" area-code="{{areaCode}}"></my-view1>

`

There is no reason the above would not work, assuming those property names were used in the listings-drawer element.
