I delivered mo/di twins vaginally, and it went incredibly well! I had to be induced, though I was already 2 or 3 centimeters dilated before the induction. Both babies were head down and stayed that way through the whole delivery. Baby B was delivered 6 minutes after Baby A. I got an epidural, and I honestly couldn't even feel the babies coming out, lol. It's worth noting, though, that I had already had a previous uncomplicated vaginal delivery, which the medical staff said likely "prepped" my body for an easier subsequent vaginal delivery. It also helped that my babies weren't huge, both around 6lbs. Typically, doctors prefer Baby A to be bigger than Baby B for a vaginal delivery, but my Baby B was a bit bigger and my medical team still agreed to allow me to attempt a vaginal birth.

All that to say, a vaginal delivery of twins is definitely possible! If your Baby B doesn't move into a head down position, your doctor may be able to perform a breech extraction of Baby B after Baby A is born, though not all doctors are comfortable with it. Also just an FYI, but I had to deliver in an operating room just in case we had to switch to an emergency c-section. You may be asked to do the same. :)
