Indeed, there is the PA+ supply voltage on the IRF510 drains during receive.
But zero drain current because the IRF510 gate voltage is zero
and nowhere else for the PA+ supply to go.? Not so much as a bias or feedback resistor.
So those IRF510 FET's are already doing the job of the extra FET that you had proposed.

But that does not remove DC from the finals.? I did not notice that the bias was dumped during receive.? That is my error.??
