What do you think about playing Electric Dreams the other way around, using Leah and Styles as PCs? It might work? Sure there would be some work to create other NPCs, and rules for the Replicant Underground, (a sort of mirror re-skin of the LAPD-RDU?...)
Aside from all this work, the only flaw is the forcing of Leah killing the partner at the Snake Pit, but as a GR I could get Leah to a high stress level and then take command of the PC and simply describe how Leah sees her hand raises, points the blaster towards her partner and shoots, as if she were a spectator of his own actions...
Edit: Better wait the new expansion "Replicant Rebellion"?
