Can pixelRL be combined with GAN?

Currently, pixelRL cannot be directly combined with GAN because the gradient information from a discriminator cannot be backprogated for the agents.

Thank you for your answer!!
I also have a question, if I use pixelRL as a generator and add a discriminator to generate reward, using WGAN reward instead of L2 reward and updating WGAN loss when updating A3C loss, is it feasible? I want to know what you think

In order to train pixelRL as a generator, you need pixel-wise rewards. If the discriminator can generate pixel-wise rewards, your idea will be feasible.
