Perhaps the most popular flats, Daddario Chromes, do not have a tapered B string, are .132 gauge and happily work with the famed Warwick 2 piece bridge on my Corvette $$.
What you will find, though, is that you will have to move the low-B side of the 2 piece bridge's lower part farther into the bass body to accommodate the large gauge.
You do that with the 3 side by side allen screws on the upper part of the bridge as you face it while holding the bass in a playing position. Consult the standard generic Warwick Bass Manual for how to lower that side of the lower bridge piece....it's easy.
I confess I am a little suspicious of tapered B-strings. I believe in my case it was responsible for a B string I could just never seem to get intonated properly and I saw the same thing on the two sets I had.
