I'm not aware of any 40"+ wingspan plans from FliteTest, if it exists it would be community plans somewhere.
Usually resizing to 140% will get mini pods to full pod size. Only issue would be A/B/C folds would be too large and likely have to cut excess paper off. Play around, and share your experiences with us.
