Hi Jonathan,
you cannot switch to a different theme while changing languages within a viewport.
There are basically two possible approaches to this problem:
1)
You adapt your theme so it evaluates the $languages property and then render the language-specific parts inside your theme in a different way.
See here:

2)
In case you also use Scroll Versions you could publish the individual languages to separate spaces, create individual viewports for these
spaces and then implement the switcher yourself. This way you could set up different themes for each viewport.
Since in 2) the linking can get complicated I'd suggest you first try 1).
Let me know if you have any further questions.
Cheers,
Jens
