Scenarios for an Accelerator & Esther Fanfic

About a month and a half ago, I completed my first Toaru fanfic, and have been putting off any other writing projects to focus on school.

But in the meantime, I've been thinking about writing an Accelerator x Esther fanfic once the school year is out, and this is my current brainstormed plot:

!Following the end of CRC's rampage which ends up involving Accelerator getting out of prison to personally help Touma put down the magician (Whatever or not this is actually true depending on GT9, we can talk about that when the time actually comes), Accelerator steps down as the board chairman following a loss of confidence. As he packs up his things and moves back with Yomikawa, he is however approached by Esther Rosenthal who wants him to help her with a few problems around the world involving 'undead anomalies.' As the two travel between nations, Accelerator starts to realize that the previously naive Esther seems to hiding something more than she is letting on.!<

Thoughts? Questions? Any other scenarios you guys may find interesting?
