"Dampers playing" feature modelling - suggestion

On a real piano when playing middle-low - low octaves pressing a "silent" key makes a very subtle pitched tone for each key pressed caused by triangle-shaped dampers friction upon a string. It would be nice to have this modelled in Pianoteq. A kind of a "ghost music".

Also, can't check it by myself, but someone who got a continuous pedal, is it possible to make a "thunder" effect caused by pedal only when you release the pedal very fast causing all the dampers hit the strings hard followed by momentarily lifting them up by pressing the pedal?
