Changing the Couples feature

This is an issue Ive seen a lot of us dealing with. Im currently trying to change it into a buisness listing Seperate from members and its turning out ok, the one problem Im running into however is removing the double picture/second person. I was able to remove it from the Join page by changing the following in  join.php
$aTableParams = array(
'double' => $this ->bCoupleEnabled,
'second_disabled' => $this -> bCouple
I changed enabled to disabled, this works for the join page but thats it. anyone know how I can remove the second person picture and name completly?
