BuddyPress.org

@christinarule nice site. After installing and activating BuddyPress, you coudl install and activate Buddy Template Pack https://wordpress.org/extend/plugins/bp-template-pack/ There are steps to go through with the Template Pack plugin and based on your theme, you would have to change the container divs of files within Template Pack. It’s not easy but it’s do-able.

There is a BuddyPress demo at http://testbp.org/
