If you want to dig into it, I believe this is the core project for the translations.
I’m willing to bet you could work something out to make it work
Otherwise there’s always selenium which I imagine would include functionality to do the page translations.
+1 for interest!
If not natively, I bet you could work something out with headless mode, perhaps.
