Does it matter what kind of keeps are around castles?

Quick question, because the orcs have no winter castle that matches the keep in the map editor, which really ticks me off. If I used the keep from another set (with no castle) and the other castle from the other set, would it still work? :

Thanks,

Don't worry, the differences between the various castles and keep are merely aesthetic (except some of them do give slightly different defences to particular units e.g. swamp castle gives more defence to swimmers).
You can mix and match them as you want.
