You mean six boxes as 3 per row and 2 rows?
Possible, you have to duplicate the php calls in home php like this
...
<div id="frontleft">
<?php include(TEMPLATEPATH."/inc/article4.php");?>
</div>
<div id="frontmid">
<?php include(TEMPLATEPATH."/inc/article5.php");?>
</div>
<div id="frontright">
<?php include(TEMPLATEPATH."/inc/article6.php");?>
</div>
of course you have to duplicate article php one to 3
to article4.php, article5.php and article6.php,
then adjust the wordpress loop in each template
like this
article4.php
php query_posts('showposts=1&offset=3'); ?
article5.php
php query_posts('showposts=1&offset=4'); ?
article6.php
php query_posts('showposts=1&offset=5'); ?
