Doesn't seem like a good idea to remove them - regardless of LPS retraction concerns (something that's not at all common).
The low-pitch stop is the only thing that prevents the blades from moving into beta range in flight. The list of possible prop malfunctions goes up dramatically w/o the LPS. Additionally, w/o the LPS, NTS would no longer function normally during deceleration increasing the likelihood of overspeed, pitchlock, & fuel topping in a critical phase of flight...
Seems highly unlikely they'd remove one safety feature & effectively disable another that leads to all sorts of additional problems...
