Jack, the device the OP is referring to precedes VHS by more than a few years. I know because I “edited” a show using two of these machines in the early 70’s (yes, I’m old!!). Mine were Sony but basically the same machine.
Having said that, your suggestion should work ok.
If I was the OP I’d try and find and ADVC-300 for it’s TBC functionality.

To the OP, given the age of the tapes, I sure hope they’re still playable. I had some at my old work place and we considered doing what you’re doing but found that the heads plugged constantly during playback. In my opinion, it’s worth the money having an outside company who does this all the time to do the job for you.
