We (Ahmadis) believe Khaatum un Nabbiyeen to mean Seal of the Prophets and I believe this is your disposition as well. However our differences arise from the way we interpret the word Seal. You take it to mean that no other Prophets can come afterwards whereas we interpret it to mean that no Prophet will come with a new law. Therefore regarding the Promised Messiah and Mehdi, we don't go against the meaning of Khaatum un Nabbiyeen because he did not present any new law.
With your definition of Seal of the Prophets however, when and if Jesus Christ does come back to earth, you will have to change the definition to accommodate him as your definition states no Prophet can come after Prophet Muhammad s.a.w. Is Jesus Chirst (a.s.) not a Prophet and if he returns, will he be demoted from his status as a prohet to fit your ideology?
