Farthingale Sleeves?

On this website the author is making a copy of a dress worn by Elizabeth I in one of her portraits. In the construction of this dress she has made this unusual sleeve construction

I quite like the way that boning has been used to create the shape of Elizabethan sleeves, and it would look pretty inteesting witht the sheer fabric on top, so the arms would still be visible. However, i can find any historical evidence behind these sleeves as construction techniques. However, in The Tudor Tailor book, it does have smaller puffed sleeves shape being created using Boning, so perhaps this idea is not too unrealistic.
