Lots of potential with this setting. It just doesn't have to be the movies and game timelines they connect, they could very well link the Generation 1 series, Beast Wars, and the others as well if the Dark Spark allows interdimensional travel...
EDIT: Wait, Beast Wars is actually a part of the G1 timeline, it's just in the distant future. I guess you could try for the Japanese versions or the Transformers Prime timeline, that could work.

Would you believe I never fully watched the original Indiana Jones trilogy? I gotta correct that someday.
