Why would you want a paypal button to do that? The only need for a paypal button is to direct you to paypal.com to pay for the purchase, what you are asking for looks like just a registration button or a profile creation button. You would be much better using a separate button for that.
You could use a paypal button for it if you wanted but it wouldn’t be through s2member, you could just take the image of the paypal button and then link it using the “a href” html code to the new page. But again, it would defeat the entire purpose of a paypal button.
