You need to explain better what you want to accomplish because the only difference of a permalink activity and one in a loop is avatar size. You can make the avatar any size you want using defines or passing arguments to avatar

`define ( ‘BP_AVATAR_THUMB_WIDTH’, 50 );
define ( ‘BP_AVATAR_THUMB_HEIGHT’, 50 );
define ( ‘BP_AVATAR_FULL_WIDTH’, 150 );
define ( ‘BP_AVATAR_FULL_HEIGHT’, 150 );
define ( ‘BP_AVATAR_ORIGINAL_MAX_WIDTH’, 640 );
define ( ‘BP_AVATAR_ORIGINAL_MAX_FILESIZE’, $max_in_kb );`
