I’m looking to do the same thing. Would you be willing to share how you did this? I would greatly appreciate it.

Edit:

Never mind, I already figured out how to do it. For anybody else looking to do the same:

Open buddypress-members-only/buddypress-members-only.php in the editor.
Look for this line:

function buddypress_only_for_members()
{
	if (is_front_page()) return;

Below that line you can add the following line:

if (is_page( array( '42, 'about-me', 'Contact' ) )) return;

// Returns true when the Pages displayed is either post ID 42, or post_name “about-me”, or post_title “Contact”. Just add your own ID’s, slugs, or titles of the pages you want to be shown without having to log in.
