A: We’ve had this question in several different forms so far, so I’m tweaking it to make it generic. We’d say NO on this one. For example, if Batman is in play, it’s just not possible for Bruce Wayne to be somewhere else, even for an instant. Same with Yolanda/Saffron/Bridget. The Doctor is a bit different, but we think it’s cleaner to keep this working the same way as the others. Blinovitch prevents you from actually having any earlier Doctor for any amount of time if a later one is already on the table.
