I think you can accomplish this pretty easy using TSmuxer + BDsup2sub, working on subtitle file alone. I've done it multiple times.
In TSmuxer, you just need to slipt the file in the segments you want to keep, then load them on BDsup2sub to adjust the delay, then you can joing them back in TSmuxer.
It's pretty straightforward, but if need any help just reach me here or by PM.
The good thing about this process is that it avoids OCR and doesn't change the original style on the subtitle.
