The AD is completely propelled by the will and power of the Thalmor, whose main goal is Altmer supremacy and the ethnic cleansing of Tamriel (so a human would have a bad time). The EP does not really have any ultimate goals, other than to prevent their respective homelands from being destroyed. Thus, and Imperial wouldn't join up unless they lived in those areas before the war. As the DC adopted most of its goals from the old Empire (free trade, peace, etc.), I'd say that they would be the most likely faction for an Imperial to join. Also, genetically I believe that the Imperials have more in common with the Bretons than the Nords. Nords are the descendants of the Nedes, Bretons are descendants of the Nedes with a tiny bit of Ayleid, and Imperials are the same, but with just a pinch of Akaviri blood.
