If your link scheme either links the static library entirely, or as a library (-l B.a) before the framework (-f A.framework), then after the static library is linked in to your program, outstanding externals for the base class methods will be resolved when the framework is linked in.
That sounds promising.
Will the classes defined in the static library be available to clients of the dynamic library?

You can then just add the .a file to your target as though it were any other library. You might be able to add .o files to a target the same way; I’ve never tried it. But I don’t think you need to mess with the linker flags.
