Hyalina???

Dear forum participants, My young daughter has recently taken a great interest in Macaws and will be giving a presentation on the subject at school next week. She has a very specific question: Does a hybrid Hyacinth/Catalina Macaw exist? We have found no trace of one online, but she pleaded with me to contact experts to see if anyone had ever encountered such a bird. Can anyone help me out? Many thanks for reading!
