Can most definitely be done.
Should it be done? Different question.
Was it done in the past? Absolutely.
There is no such thing as "NTS disconnect" - perhaps you're confusing the safety coupling with NTS? Regardless, you'd not reach -6000"/lb of torque unless at high speed, so no decoupling would occur.
Blade hang-up is another matter entirely and is unrelated to selecting reverse in flight.
As a semi-related tidbit of near-useuless information, newer models (H3 & up) have "beta lights" letting you know low-pitch stop has retracted and reverse can be selected.
Again, just because it can be done, does not mean it should...
