I have changed my search strategy somewhat(not trying for an exhaustive search) and found a solution with 3 As(including 0) and 30 Bs.

One of the big things that helped was only looking at As divisible by primorials. I am finding more and more Bs as I increase the multiplier to larger primorials. I suspect that it might be possible to construct solutions of any size by increasing the primorial. I haven't written the code yet to check whether these would extend to nice solutions with 4 As. Current results look promising in that regard though.
