Remove "your address" from registration process

The simplest way I can think of is to edit /frontend/register/billing_fieldset.tpl, and add conditions to each field which change address fields to hidden type and place some placeholders into field values to pass validation if user is on registration page. For example:

The problem is that Shopware redirects registered users to the 3-rd checkout step, where they can instantly click order placement button without noticing that their address is composed of placeholders.
