Hi Thomas,
Sorry no, there is no option to use electron scattering factors.  The molmap command does treat different elements differently, however:

Each atom is described as a 3D Gaussian distribution of width proportional to the resolution and amplitude proportional to the atomic number.


There is a also a molmap command in ChimeraX, and it works the same way as in Chimera.
