Comment:

 I use this filter:

 {{{#!php
 <?php
 add_filter('template_include', function(){
         return locate_template('test.php');
 });
 }}}

 And I have white page. I think that should be this if:

 {{{#!php
 <?php
 if ( $template = apply_filters( 'template_include', $template ) ) {
                 include( $template );
         } elseif ( current_user_can( 'install_themes' ) ) {
                 $theme = wp_get_theme();
                 if ( $theme->errors() ) {
                         wp_die( $theme->errors() );
                 } else {
                         wp_die( __( 'Template is missing.' ) );
                 }
         }
 }}}

 But theme->erros return error if not exists index.php file so better patch
 is:

 {{{#!php
 <?php
         if ( $template = apply_filters( 'template_include', $template ) )
 {
                 include( $template );
         } elseif ( current_user_can( 'install_themes' ) ) {
                 wp_die( __( 'Template is missing.' ) );
         }
 }}}
