Be careful that the roundwound you use for a B string has a similar winding structure and wrap metal as your other strings so there is consistency of tone, not just brightness. I do this on my Rick 4002 (yes, "2," not "1" or "3"): Progressives E105-A80-D60 with a Pressurewound G44. The Pressurewounds have the same "Alloy52" wrap wire as the Progressives, so the overall tone is complimentary. The Pressurewound has a little less top end which keeps the G string from twanging.
OTOH, I tried a coated B string with my white tapes, and it was too zingy, so I went back to a white tapes B string.
Double bass players have done this for years, one of the more common mixes being to use a Spirocore E string, which has great definition and response, along with just about anything else on top. Everything goes with a dead Spiro E string.
