As detailed in [EscGro '13], it is possible to replace some Groth-Sahai commitments with just ElGamal encryptions (as opposed to being computationally indistinguishable whether it's a binding commitment or ElGamal Encryption / hiding commitment), which reduces the number of proof computations and proof size. Consider implementing this variant of Groth-Sahai.
