Artifacts masking without interpolation?

Is there any way to just use the artifacts masking feature without adding any interpolation? Basically, have the current frame fade in, while the previous frame fades out, while raising the frame rate so these fades aren't instant. This would be a way to make a low response time screen like an OLED have the smooth video of an older LCD using blur while not adding any new information. Or else, can somebody point me towards any way to do this.
