Customizing edu-clean theme


We are using 'edu-clean' as our home theme and buddypress default 'bpmember' theme for the buddypress part.

However, we do like how the sign-up page appears in the buddypress 'bphome' theme. Love the way the registration part appears on the left side of the page and the rest of the widgets in the centre and right sidebars.

How can we incorporate the same layout on our edu-clean registration page? I guess it uses the default wp-signup.php. Is there any way to build a custom registration page much like 'bphome' and redirect users to it?

Something tells me this could be much simpler than it is in my mind, but not sure how it can be done. Any suggestions here please?
