I've always prefered seeing the battlefield littered in my opponents dead (and a few of mine) I know that leaving them on the map can make the game run slower, so was wondering if maybe it could be an option in the expansion? Even if u just have a pile of squashed metla or something, it would help to add to the atmosphere of the game.

It unlikely to be done.
And there is a pile of reasons for that.

oh well i can hope, thx for replying
