title: Magento 2 - override layout.xml file within module
body: <p>Looking at the Magento 2 docs, you can override a base/core layout.xml file - <a href="http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/layouts/layout-override.html" rel="nofollow noreferrer">http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/layouts/layout-override.html</a></p>
  
  <p>Is it possible to do so within a module rather than theme?</p>
  
  <p>Alternatively, is it possible to bundle a theme within a module and extend that (and multiple other themes from multiple other modules) from the main website theme?</p>
