Here's a great way they can make stitch work for american audiences and fanboys and fangirls
give wdw's tiki room a nice facelift and full refurb with up to date sounds, lighting, AA's, clean sets, etc, etc
remove SGE and take the the stitch AA and put him in the stitch room (looks like the one in tokyo is the same style AA figure as the one in SGE)
anyway, the we get back our barker bird and original preshow, and even the show starts out the same, we all wake up jose and they do in the tiki tiki tiki blah blah blah tiki room
perhaps one more original number and then the when they want to use the magic fountain it doens't work and we hear all sorts of noises and stitch pops out of nowhere and all the birds are like ?! but they make friends and all the girls on the birdmobile (please don't have them wearing stitch ears) and the tikis and totem poles all sing to say 2 stitch songs with a poly theme,and then the show ends because once again the gods have gotten angry by something and evething ends as it was with "you've heard the flowers sing, etc and high ho"
that way the show is modern technologically, looks great, and is a balance between old and new.
