perhaps it could be done like I remember seeing in one of the cities. Just a different tileset from grass (though other cities don't seem to share this effect, and I'm not sure which had it)

Dormeho does that. Has the docks as the tiles for the tileset and all that. As for my take on this as a whole.

Go nuts. Do whatever. If it gives the BB Treatment, might make people more wary a bit as to where they're fighting but that's about it. I'd be bothered if I didn't see buildings around where I was fighting and it was just an OPEN AREA INSTEAD.

So sure. Yes. Sure.
