You can use a single opamp and complementary transistors at the output. This is the ultimate ClassB stage. Note that the current in the transistors Q1 is essentially leakage only when the input is at zero V. I took the liberty of running it on split supplies.
Purists will say that it will have some crossover distortion, but that is the price for having nearly zero quiescent current. Note the little dance the output of the opamp does V(oa) green trace as the signal crosses the middle.
