You would think e-sky could pull it off, but so far nothing.
It's just too complex to do economically. We're more probable to see mixed approaches like FP coaxials with a tail rotor (like walkera announced but still isn't selling) or even single-swash CP lower motor with an upper FP rotor + flybar, with or without a tail rotor.
As a sidenote, a large electric or gas-powered coaxial has
to use mechanically interconnected rotors, so CP or FP with tail rotor is a must. Imagine trying to tune TWO nitro engines with a gyro to spin at nearly the same RPM without excessive throttling up and down...
