I'd argue the easiest option is just to extend the plate.

Second option is to swap the rails and carriages (as I think Phil suggests) but its quite nice to be able to remove the spindle plate in one go with just four screws on the ballnut; it can be a pain to remove the other way round.
I did try it with the rails the other way around and I wasn't keen. I think that you're right, extending the plate is the easiest option.
