Interesting concept. A bit like "Quantum Leap" meets "Seven Days", maybe? QL had the borrowing of another person's life and identity, while SD limited the time travel to one week and was a government operation. Like "Timeless", SD used a physical time-capsule.
Delighted to hear you also agree that "Doctor Who" is the best time travel show on Earth. I love the Doctor, all of him-- er, them! Discovered reruns of Tom Baker's episodes while I was in college and took to the program at once.
