Watch the shows again and take note of the small details. Maybe there was a side character who didn't get much screen time but had a lot of potential. Also, think about alternate universes. What if Barry never got his powers? How would that change things? Another idea is to combine elements from different seasons. For example, take a villain from an earlier season of Arrow and put them in a situation with a character from a later season of The Flash.
