Just FYI I do want to support this. Rather what I would support is being able to order physical flash cards with my selection of n<=~10 language of translations.

I think this would work better than this. I would totally pay for this tomorrow (not sure how much). Maybe $5 per language?

With this interface and it showing the translations to you it's not conducive to recall, which is the process by which we tell our brains to connect/build more neurons for this particular datum.
