Simpler maybe… but wouldn’t this result in a frame literally being dropped anytime the drop frame timecode "skips”? And maybe async option could fix the synch issues or through resampler. 

Actually that would count as “change the audio speed” wouldn’t it :P Either way, I’d be interested to know how it plays back, maybe if it’s not long enough it wouldn’t be discernible.
