It is possible by adding the buttons You need again. See an example here. The function needs to be modified and copied to YOur qa-theme.php.
After that You need to change the upper margin of the class .qa-vote-one-button in the css file to 0: margin:0;
That should work for You. You just would have to change the language file as well, as the newly visible but disabled button says something that does not fit Your needs...
It will not allow You to use the newly visible second button I think. Please play around a bit..this coulld be a starting point.
Modify the following function as follows:
function vote_buttons($post)
{
$this->output('<div class="qa-vote-buttons '.(($post['vote_view']=='updown') ? 'qa-vote-buttons-updown' : 'qa-vote-buttons-net').'">');
switch (@$post['vote_state'])
{
case 'voted_up':
$this->post_hover_button($post, 'vote_up_tags', '+', 'qa-vote-one-button qa-voted-up');
$this->post_disabled_button($post, 'vote_down_tags', '–', 'qa-vote-second-button qa-vote-down'); // A D D E D
break;
case 'voted_up_disabled':
$this->post_disabled_button($post, 'vote_up_tags', '+', 'qa-vote-one-button qa-vote-up');
break;
case 'voted_down':
$this->post_disabled_button($post, 'vote_up_tags', '+', 'qa-vote-first-button qa-vote-up'); // A D D E D
$this->post_hover_button($post, 'vote_down_tags', '–', 'qa-vote-one-button qa-voted-down');
break;
case 'voted_down_disabled':
$this->post_disabled_button($post, 'vote_down_tags', '–', 'qa-vote-one-button qa-vote-down');
break;
case 'up_only':
$this->post_hover_button($post, 'vote_up_tags', '+', 'qa-vote-first-button qa-vote-up');
$this->post_disabled_button($post, 'vote_down_tags', '', 'qa-vote-second-button qa-vote-down');
break;
case 'enabled':
$this->post_hover_button($post, 'vote_up_tags', '+', 'qa-vote-first-button qa-vote-up');
$this->post_hover_button($post, 'vote_down_tags', '–', 'qa-vote-second-button qa-vote-down');
break;
default:
$this->post_disabled_button($post, 'vote_up_tags', '', 'qa-vote-first-button qa-vote-up');
$this->post_disabled_button($post, 'vote_down_tags', '', 'qa-vote-second-button qa-vote-down');
break;
}
$this->output('</div>');
}
EDIT ------------------>>>
Ichanged the code a bit as the two added lines didnt have values !!!!
$this->post_disabled_button($post, 'vote_down_tags', '–', 'qa-vote-second-button qa-vote-down'); // A D D E D
$this->post_disabled_button($post, 'vote_up_tags', '+', 'qa-vote-first-button qa-vote-up'); // A D D E D
