You might be free to do that under the license of Whonix. Not legal advice.
However, to become an official Whonix download, downloadable from whonix.org, to match quality standards, these builds would have to be created by the Whonix build script.
From Policy for Inclusion of Compiled Software - #6 by Patrick
Why didn’t I develop “Whonix freeware” style? What I mean by “freeware” style: Not a “proper” Open Source project with instructions on how to build it from source code. Why bother spending hours and hours with the development of a build script if I could just install Debian inside VirtualBox, manually make all changes by keyboard and mice, run a cleanup script, export ova, upload? Could even post instructions how I did it so anyone can manually replicate. With “freeware style” development would be actually a lot easier, faster. What’s the difference between “freeware style” development and a package that contains binaries? I am trying to demonstrate the slippery line between a clean Open Source project and “freeware style”.
On top of that, to allow downloadable builds form anonymous contributors, we’d first need:
- deterministic builds
- verification of deterministic builds
