I'm sure you could ^^
You just need to start off with a story that you like (preferably one that has some underlying themes relatable to life as a whole), and then know where you want to go with it.
For instance, in my story, the Shinigami have eradicated all of the Hollows, and have upset the balance between Shinigami and Hollows. The line between good and evil has been smudged. Light creates shadow. Power corrupts. Etc. Those are the underlying themes of my story - soon, it will be explained more thoroughly in the story itself. From the beginning, I knew exactly what I wanted to have happen: first, I wanted the Captains to experience the loss of some comrades. They've never really seen action before, and this is really the first time that they've experienced real loss. Next, I wanted the Captains to encounter Goro - to show how Hollows can never truely be eradicated, and to show that the balance between Shinigami and Hollows (or, to be more accurate, the balance between 'good' and 'evil') waxes and wanes like the Yin and Yang, and to show how hope still exists for the Captains.
I don't want to go into more detail storywise, but you see that everything in my story is symbolic, and you see that I do everything very deliberately. The settings and minute actions in my story are even symbolic. For instance, the Captains trecking through a pitch dark desert represents how they're surrounded by the darkness of Yammamoto and the other corrupt Captains. And the flares are also symbolic. The Shinigami squadron shooting up the flares represents their hypocrisy - how they're bringing "light" (symbolized by the flares) to a world of "darkness" (symbolized by the pitch black night) in order to eradicate what they see as "evil" (the fleeing Captains), although that "evil" is actually "good", and although the Shinigami squadron itself is the "evil".
Urahara's death and mutilation mirrors the insignificance of the fleeing Captains' lives. Although the fleeing Captains have worked for hundreds of years to get to the position of "Captain", all of that was made irrelevant by Yammamoto's betrayal in the blink of an eye - their hard work was all for nought. Likewise, Urahara was changed from a proud, strong wiseman into a pile of bloody flesh in an instant - in the end, he is nothing but blood and guts. People are simply just blood and guts in the end, no matter what they "accomplish" in life.
If that all makes sense xd
1. Solid story that you like with identifiable universal themes
2. Things that you want to have happen in the plot
3. Symbolic details that relate back to the themes of the story
