Need some ideas for my next Fanfic

I want an opinion from my watchers. I was thinking of some ideas for a new fanfic that I'm gonna do and I was thinking, should I make another crossover of Crash and Spyro? I was thinking for the intro, using the scene in which Evil wins in Crash Bash, and when Aku Aku tells Crash and Coco to run, they accidentally go through a portal which takes them to Spyro's world. Also, I would like to know what characters that you think I should include. If any of you have advice, I'm willing to listen to it.
