This is not a bad idea if the timecode was on Free Run and not Regen.
If on Free Run you can match the timeline’s TC to the first clip and then lay down each clip to match the timeline. When done you have a single movie file with black gaps where you stopped recording.
If you other camera was in Free run also you do the same for it using its own TC.
Then you have two solid movies that you should only have to sync up once. And you could do that with the in point or the aux TC method.
Of course the key is how TC was recorded.
