If BSG were to be redone now, I'd do it like this, with 5 seasons running at 10-12 episodes each. Each episode would be separated by about 5-10 years of time in-show.
S1: The end of the thousand yahren war, the loss of the colonies, the exodus, the discovery of Kobol.
S2: Finding the Pegasus, temporarily taking the fight back to the Cylons, followed by being overwhelmed and a second exodus.
S3: The desert. This whole season embraces life in the rag-tag fleet, the misery of it, societal adaptation, the search for resources, and pursuit by the Cylons.
S4: Count Iblis and the War of the Gods. The colonials attempt to settle a planet under Iblis' guidance. It is a disaster, and the Cylons nearly destroy the survivors. Third Exodus.
S5: The refugees encounter Terra after some signposts from the City of Lights, press on past, and discover an even more advanced Earth with a large interstellar Federation or some such. These people have advanced AI and anti-cyber capabilities, and the pursuing Cylons are destroyed in a final confrontation. What's more, a cyber-mole works back through the entire Cylon civilization, destroying them and ending the threat forever. (Shades of Hugh the Borg in TNG) Humans win!
