Okay, now knowing how big the toy is, here is a comparative view of the dropship and AT-TE. As you can see the dropship would have to be HUGE. For such a "niche" vehicle as this, I don't see anyway of Hasbro making this (and affordable-given the most anyone would want on average would be one).

Though, I do look forward to seeing someone make a cool custom of this. The current gunship is too small to make it work, but I can see someone using it as the basis for the custom.
(Excuse the crude job of the graphic but I wanted to get this posted quickly and I'm on lunch and lunch is almost over with....)
