I guess you could try something like this

PHP Code:

require_once(DIR . '/includes/class_bbcode.php');
$newUserTitle = $post['usertitle'];
    
//Use [c] for [color], it will save some characters from the usertitle limit.
$newUserTitle = preg_replace('#\[c(.*?)\](.*?)\[\/c\]#','[color\1]\2[/color]',$newUserTitle);
    
$bbcode_parserx = new vB_BbCodeParser($vbulletin, fetch_tag_list());
$newUserTitle = $bbcode_parserx->do_parse($newUserTitle , true, false, true , false, false, false);
    
$post['usertitle'] = $newUserTitle; 


You could use hooks like:
postbit_display_complete
profile_complete
etc...

The hook will change according to the location you want to enable it.

I'm not sure if this is going to work, as I haven't tried but please post your results here after testing.
