Integration with Realname Registration

Into the user registration form, the Realname Registration module replaces the username field with first name, middle name (optional) and last name fields. Then, the username field value is automatically builded from the contents of that other fields provided when the user fills out the form. All that fields are tokenized.

So, I wonder how easy would be to integrate support for Realname Registration in Profile2 Regpath forms displayed in paths customized by role.

At this moment, Profile2 Regpath needs explicitely the username value filled out in the appropriate field to validate the registration form –but Realname Registration is hiding this field from the form to build the value internally. This prevents to validate the form, the alert "You must enter a username" is displayed and in fact the user cannot enter it.

Since I'm not a programmer, I don't know how to build a custom module or submodule to integrate both modules.

Any help would be pretty appreciated. Thanks!
