Can there be a good way emigrate Joomla 1.5 customers to Wordpress 3.2? I have already effectively migrated the majority of the content using this plugin but have to migrate the customers, too.

I do these conversions in the database level. It's only a matter of mapping the fields within the two schemas and creating place SQL sentences for Wordpress in line with the info within the Joomla database. However, so the passwords can't be migrated due to the various encoding system. You need to just assign an imitation password to every user and request these to totally reset the password the very first time they struggle to sign in.
