It is trivial. You let the one side of the hybrid direct couple the signal
and let the other side of the hybrid capacitively couple the signal. THe
downside is that the DC receiver has to be on and working to let the AC
receiver work. A bit more work with diodes and chokes can be done as a
work-around to let either of the receivers power the active antenna.

This is not quite as simple as just hybrid or resistive RF power divider
because of the 5V for the LNA inside of many GPS antennae. More info is
needed on the receivers and the antenna.
