Dragon as a emergency return from orbit vehicle?

Lets imagine soyuz having another problem where replacement birds cant
launch.

Could they send up a dragon and use it as a pure emergency return
vehicle? Say with 2 space suited crew members some emergency oxygen,
all remote controlled. The crew would enter dragon perhaps with
inflatable couches, seal the hatch and be returned to earth.

wonder how fast a departing dragon could in a emergency be re entered?

This might enable during a soyuz problem to leave 2 ISS crew members
for skelton operations while returning everyone else by soyuz.......

the remaing 2 crew members would still have a way off in a true
emergency
