I'm a bit concerned about this change, because my assumption—although I never tried to validate it—is that KeSetTimerEx() should probably act as a fence, i.e. it shouldn't be possible for an earlier callback to execute simultaneously or after it's returned. In this case that could result in a non-periodic DPC executing twice, which seems dangerous. Note that 1/3 won't actually help you, because we could already be in ke_timer_complete_proc() but not executing the callback yet.
