Can I convert a Wordpress (GPLv2+) theme to another CMS theme?

Question

Copyright

Is it permissible (legally) to take a free theme from wordpress.org, leave html and css from it, throw out all php scripts, convert it to a theme of another open source CMS (not PHP), and put it under the same GPL 2 license in a public theme directory for this CMS? With an indication of the original authors in the Readme or License, of course.

Answer 1

Yes, the license allows it.
You can just read it, it's simple.
