We will see because we are well on our way of LLMs being able to translate whole codebases to different stack without a hitch. If thats OK than any of the copyleft, open-core or leaked codebases are up for grabs.
If you order an LLM (or a human) to do a straight 1:1 translation, you'll sort of pass one test (it's a completely different language after all!), but fail to show much difference wrt structure, sequence or organization. I'm also not entirely sure how good of an idea it is technically. If you start iterating on it you can probably get much better results anyway. But then you're doing real creative work!
