I think it's better if you create a new module position next to the banner, then load that module "Sign In | Join Free" to that new position.
-Create a new position: you can google, there are plenty guides for this.
-Load new position next to banner by opening the file: /templates/ja_simpli/index.php and add this code:
<?php if($this->countModules('headmenu')) : ?>
<!-- Header Menu-->
<div class="headmenu span2">
<jdoc:include type="modules" name="headmenu" style="none" />
</div>
<!-- // Header Menu-->
<?php endif ?>
'headmenu' is new position name
-In the code above, you add 'span2' class to you need to reduce the width for banner position to 7: https://prnt.sc/pe7idb
