YES PLEASE! I for one would be delighted with this design!
Interesting that no steelbook has been announced for this movie yet... I'm sure there'll be one but Disney's pattern is to announce the steelbook in conjunction with the theatrical release (give or take a day or two). At least, that's been the case these last couple of years for Pixar and Animation Studios releases (Zootopia / Big Hero 6) - as well as Marvel and Star Wars steels...
Thanks for sharing your concept - and fingers crossed we get something as nice as this (I remain sceptical!)
