Unless, you must have disk brakes, that's another thread though.
I have used a couple of vintage MTBs for this very same purpose. I would have to disagree with you. Disc brakes aside, there is a huge difference in going to 700c wheels and a much lower BB. There are other factors, all in favor of the modern gravel bike, but the two I just mentioned are more than enough for me when it comes to all-day riding on any kind of road. YMMV, of course.
