But the control actuators still need to be powered, and that comes from the cabin.
Actually you don't need to slice the cabin there. you can pretty much just slice it off where it meets the body. Keeping the entire rear cabin bulkhead. And separating it simply from the wing spars. This leaves the entire front heat shields, the front parabolic nose for handling the extreme speeds that it will already be at. The nose contains large spheres of propellant, and with the intact thrusters it would be able to keep itself oriented correctly into the wind during separation and after.
Wireless controls are always subject to more interference
