Since Warwick tailpieces can be a tight fit for some brands of string, I would have thought any Warwick string should fit that.

A good suggestion above. I have had a look on the well known internet auction site - individual bridge pieces are available, unfortunately not in the same pattern as yours. I would contact the bass manufacturer and explain the issue, see if they will give you a bridge piece which you can then have a go at drilling out. Much safer off the bass, no 'oh dear' moments. In the long term you want to be able to use strings of your choice, not be limited by bridge.
