Hi Wayne, you will need to do some research and see how high the rosewood bridges are and compare it to the PBG supplied bridge.
I would guess the heights should be fairly similar but have never installed a rosewood bridge so can't be certain.
If you search the build diaries for the ES-2V model have a rosewood bridge the builder maybe able to supply you this information or flick Adam an email to see if he can measure it from a kit.
Another modification I think you will have to plug the existing bridge holes as I think these rosewood bridges are fixed in place with the smallish thread will screw into the body, a much smaller thread size than the standard approximately 12mm bush
I just found a link to a current ES-2V build so maybe you can PM Mattyeales
