I know what you mean but I think, in this instance, trading back would also be in part about adding other top 150 picks or being able to move back
up later.
Jourdan has her final mock that shows them, for example, trading back
twice from 36 (ultimately to 53) but in the process ending up with 5 picks in the top 133 (53, 69, 77, 81 and 133). That's the type of moving they need to do. In fact I'd do more moving back up because in her mock they still have 7 picks in the final 3 rounds. I'd package a couple more to get another top-150 pick.
