Create just one .tpl.php file for several nodes? I created these .tpl.php file for two node:

html--node__39.tpl.php
html--node__14.tpl.php

Question: can I create just one file for both node?, something like:

html--node__39&amp;&amp;14.tpl.php
Here is an example to change the template dynamically on node type with a preprocess function. Of course you can also use this based on nids. https://www.drupal.org/node/1142800
