I've been experimenting with being able to install CiviCRM into Wordpress with Composer. Created PR to add a composer.json into the civicrm/civicrm-wordpress repo https://github.com/civicrm/civicrm-wordpress/pull/347 As a proof of concept I created a composer template https://github.com/jackrabbithanna/wordpress-civicrm-composer-proto which makes use of it. Issue for ideas and discussion, and to group further work that would be required.
