Google Search

Is there any way to replace the search field with the Adsense search code? ie

<br><br>
<form action="http://www.google.com" id="cse-search-box">
  <div>
    <input type="hidden" name="cx" value="partner-pub-xxxx:xxx" />
    <input type="hidden" name="ie" value="UTF-8" />
    <input type="text" name="q" size="55" />
    <input type="submit" name="sa" value="Search" />
  </div>
</form>

<script type="text/javascript" async src="http://www.google.com/coop/cse/brand?form=cse-search-box&lang=en"></script>
