Otto has already created this plugin: https://wordpress.org/plugins/theme-check/ which checks Themes to make sure they are up to theme review standards. So how about making this plugin mandatory and then taking it one step further and have Otto's plugin do any/all additional automation that is currently being done by human Theme auditors and once Otto's plugin is run on a Theme and the Theme "passes" then automate that "pass" by notifying a Theme auditor that the Theme has "passed". Of course a side by side data/code change comparison would also have to be done at final Theme audit to ensure that nothing was changed after the Theme "passed". Seems like this would be a smart way to go and build on.
