I think it seems like a great idea. It would expand on the final tag well and would play with the Bluths as public figures which was always one of my favorite (and I think underrated) aspects of the show.
Word is that the official announcement of the project could be only weeks away so we may not have to wait too long. But what do you think? Would you be satisfied if this was the plot that brought us on our return trip to Sudden Valley?
