Im confident that Hasbro will hear the fans and give us a true R5D4 (Hey, I want one too!
) Like you said, it wouldnt take a lot of work.
Is the scoring -just- paint, or is their molded damage? It's so black I cant tell. In the Star Tours droid there is a big gaping hole where some of his panels were removed.
As far as the skeezee bird, while I like it, I do admit it would have been one of my last choices. If it were to be another droid, the gonk would have been great. There are a few other droids as well; I would have even prefered the red version of the R2 unit already made.
I cant speak for any other locations, but I do know that the skeezee bird is at Star Tours in MGM Florida (or at least the last time I visited which was about a year ago). He sits at the top of a doorway, out of easy view, and bows back and forth. Because of his being a bird originally, he still has the programmed bird movements (but no sqwaking). He was placed atop a doorway (or entryway, whatever you want to call it) as a subtle reference to other birds in Disney rides that sit looking over the ride entrance (The Tiki Room (when it still existed), Pirates of the Caribbean and The Haunted Mansion also all have "guard" birds, as well as a lot of other rides).
Also, according to some older Disney collectibles magazines as well as some conversations with Disney product purchasers, not only is this line supposed to be carded on the blue Saga cards, but also Series 1 and 2 are due to be recarded. The recarding is still up in the air though. Ultimately, they want their displays to match and think green and blue cards are going to throw off the casual customer, thus they want to take everything over to blue (which ties it to Star Wars right now)
