One option might be for you to have two listings. Listing #1 is one bedroom; Listing #2 is for both bedrooms. This way, the party that books continues to have the luxury of a private bath.
A second option would be to add an addtional third listing exclusively for for bedroom#2. The disadvantage of this is then each individual bedroom is listed as "shared bath."
You could experiment with this and see which option produces the highest revenue. Personally, I would try option #1 initially and see how often both rooms are booked together.
