It's not possible, because EM field doesn't affect all particles.

If we stick 2E15 electrons together in a long line, then it will start to rotate too due to differences in gravitational field at inner and outer segments of the line. Something like that must happen to an 1mm wide photon too. I'm not talking about orbit of those electrons around object, but about rotation alone.

It's not the EM field, but gravity. > If we stick 2E15 electrons together in a long line, then it will start to rotate too due to differences in gravitational field at inner and outer segments of the line. Just look at an individual electron. Why would it curve? It's sufficiently point-like for the gravitational field gradient to be negligible.
