Speaking of Bunnies... (Warning - fairly long)

[Sirrocco]

It could be interesting. It's an extreme change/heavy crossover fanfiction. Even more than most stories, those are all in the execution. If it inspires you, go for it. Worst case, you get some experience writing, some useful feedback on your writing style, and an amusingly bad piece of writing to groan about theatrically a few years down the line once you've improved. These are not bad things.
