That's possible, just change the adv_portal_ecdownloads template to what you want
This should work:
HTML Code:
<tr align="center">
<td class="thead" width="25%"><span class="smallfont">Latest Files</span></td>
<td class="thead" width="25%"><span class="smallfont">Most Popular Files</span></td>
<td class="thead" width="25%"><span class="smallfont">Top Contributors</span></td>
</tr>
<tr align="center">
<td class="alt1">
<fieldset class="fieldset" style="margin:0px 0px 0px 0px">
<legend>Latest Files</legend>
<div style="padding:0px">
<table cellpadding="0" cellspacing="0" border="0" align="center" width="100%">
<tr>
<td width="100%">
<table cellpadding="2" cellspacing="{$stylevar['cellspacing']}" border="0" width="100%">
$dpanel_latest_bits
</table>
</td>
</tr>
</table>
</div>
</fieldset>
</td>
<td class="alt1">
<fieldset class="fieldset" style="margin:0px 0px 0px 0px">
<legend>Most Popular Files</legend>
<div style="padding:0px">
<table cellpadding="0" cellspacing="0" border="0" align="center" width="100%">
<tr>
<td width="100%">
<table cellpadding="2" cellspacing="{$stylevar['cellspacing']}" border="0" width="100%">
$dpanel_popular_bits
</table>
</td>
</tr>
</table>
</div>
</fieldset>
</td>
<td class="alt1">
<fieldset class="fieldset" style="margin:0px 0px 0px 0px">
<legend>Top Contributors</legend>
<div style="padding:0px">
