OMG, are you serious? you made Akechi pack, and it means I can replace Saito with Akechi and sack Oda?
It will be most amazing change. I'm not sure if you are aware of it, but you are creative genius indeed.
I love to see his Kamon in actual campaign. I wish I had some modding skill just like you(I tried, but it was not easy at all)
I'm so angry because I have to wait till get some upgrade with my computer to start my new campaign. I can't wait for it!!
Akechi's Kamon is a Japanese Bellflower(Kikyou), and Oda Nobunari, the famous figure skater and who claims he is direct descedant of Oda Nobunaga,
said in TV show that his wife never put Bellflower in the house because it is crest of foul traitor who murdered their ancestor.
and I just remembered...what about Changing Saito clan's Kamon into famous Dosan-nami(Dosan wave)?

See Japanese version, and you can see Dosan's Kamon.
Dosan is one of most treacherous Daimyo in Japanese history, and it will be shameful display if we miss his infamous Kamon.
I have only limited information regarding Saito clan's Kamon, but I doubt it should be Kikyou Kamon just like Akechi's.
Saito Dosan was one of Samurai serving Toki clan, master of Mino(and treacherously betrayed them to gain Mino province afterward),
and his son Yoshitatsu, who murdered Dosan(just like his father did to his master) claimed he is not Dosan's son, but Toki clan's offspring,
and Akechi Mitsuhide claimed that Akechi clan was branch of Toki clan, so Saito clan may use Toki's Kikyou kamon, but not for Dosan.
He never said he is successor of Toki clan, but actually he was ursurper of it.
It should be after Dosan's death if they using Toki's Kikyou crest, from the time his son Yoshitatsu got big coup against his father and considered he restored Toki clan.
Dosan was doing quiet all right in 1545.
