Blood Dolls in later maps

While I appreciate the creation of extra blood dolls in the game, one of the key values of having blood dolls in that later maps, making the experience worth more then simply convince gaining, was the fact that the later blood dolls had a much larger blood pool. This still is true for the original blood dolls but the new ones are still little more value then the SA ones, hardly worth the 9 points of seduction needed for china town. Any chance their blood pools could be increased?

Makes sense. Not everyone on the street has PhD.
