I think you'll be fine. At most the E and G strings would be about 1mm further in from the edge of the fingerboard at the last fret. Depending on what sort of notches are in the saddles of the new bridge, you may be able to file them over slightly, on the larger strings at least. Most likely though it will be fine as is. Generally bass strings are far enough away from the pickups that polepiece spacing won't be an issue. I'd say just go for it.
