Expanding the search function

Hi Guys,

I have integrated one of my enfold sites with ChamberMaster: https://www.rsgchamber.com

I am finishing up some edits and widget integration and will need to incorporate the ChamberMaster search. I would like to keep the clean look of the search icon I currently have in the header but make that module function so that it searches both website and chambermaster site as well which is a subdomain: https://business.rsgchamber.com/

Below is the widget code they provided. Is it possible to combine the enfold search and the CM search into one global search in the header? Possibly with a plugin or script?

<div id=”mni-search-1518586367593″></div>
<script type=”text/javascript” src=”https://business.rsgchamber.com/Content/Script/SearchWidget.js”></script&gt;
<script type=”text/javascript”>
