I'll start.
A possibility
"Is there something wrong, Rider?" Asked Sakura.
"Nothing, master." Rider scowled, her eyes glared at her as she feels sick looking at the mere shell of her former master. Who can blame her? The appearance of the white haired girl in front of her is merely a front for a sinister being.
The servant refuse to refer the her master as Sakura as the poor girl has long vanished from her own body. Matou Zouken has completely possessed his own granddaughter during the last war many many years ago, before the beginning of The Universal Century calendar.
"I'm glad to hear that." It's even more disturbing that Sakura's voice no longer contain her own but it is being used by that old magus to communicate with Rider.
Also, she can't help but feel threatened every day since servant assassin is lodging in the same place she does along with her "master".
Even though many years have passed since the last heaven's feel, Rider still felt obligated to serve, despite doing it begrudgingly. Due to her riding skills, she has been piloting Earth Federation mobile suits that she hijacked from their bases, mostly covering up as a Zeon spy during the One Year War. She has been reduced to a mere bodyguard of an individual she wish she can shoot him down with a beam rifle.
Why is she doing this?
Because the legend of Heaven's Feel has been spread across the world and Zouken believes that both the feddies and the zeeks would want to get their hands on it. Zouken with pride of a magus and self-serving bastard wants no one else to have it.
and if possible ,there is a chance that Sakura can still be saved..............
Don't mind me scaring all of you

Heaven's Feel is 2004, the calendar ends in the year 2080 (Strange last time I checked it was 2045), adding with 79 years into UC Calendar and according to my original idea Shirou's story takes place after Char's CounterAttack.
Rider has been living with her "master" and assassin for that long...........
Imagine living with the old man of the mountain and a female master possessed by an old man and using her sweet voice to talk for more than a 100 years.........
