I am joining this project but do also initiate a project trying to use T5 for translating between Norwegian Bokmål and Norwegian Nynorsk (Model to translate between Norwegian Bokmål and Norwegian Nynorsk 1). There might be some overlaps here, at least since we can some of the same corpus. If anyone in addition also want to also work on a Scandinavian Seq2seq model, show your interest in that thread. (Unfortunately I do not think a Scandinavian parallell corpus exists…)
