Great Idea!
One important thing is to define the scope of the project, specifically which and how many languages to use. We should decide this based on the time and compute constraint so that the project can be finished in time 
It’s also possible to use other multilingual models like mBERT of XLM-ROBERTa, but as those are encoder-only models we will need to add a cross-attention layer in it.
I’m officially defining this project!
