Yes fantassy battles are welcome, (as long it is not entirely AU/OC stuff). We call such battles predictions around here. Just post them as blog posts and use the word "prediction" in the title.

If you have something which is entirely off canon then you can use http://shipoffools.wikia.com/wiki/One_Piece:_Ship_of_fools_Wiki to post that.
