Battlestar Galactica in the 25th Century

After watching a few episodes of Buck Rogers in the 25th Century this week, it struck me that the show shared a lot of commonalities with the contemporaneous Battlestar Galactica: creators, behind-the scenes personnel, ship models, sound effects. Buck Rogers outlasted Battlestar by a few months, but Glen A. Larson must have seen that Buck Rogers would soon follow suit. I wonder if he ever considered a fun series finale for Buck and a belated farewell for Battlestar Galactica; he could have had the Galactica finally reach Earth in the last episode of Buck Rogers. How cool would that have been, to see Gil Gerard and Lorne Greene team up to beat the Cylons back from post-holocaust, 25th-century Earth?
