Here's a link that backs her interest.

It's a difficult one because you know that some would abandon Doctor Who as soon as she was cast regardless of the actor chosen, let alone give her an episode to establish herself as The Doctor.
I'm not advocating for a female Doctor either but after thinking about this for a while I do wonder if this is inevitable tbh. Natalie would be one of my choices should they go that way, I'd rather her than an overly comedic actress who would overplay it. It would already be considered a gimmick or a 'jump the shark' moment as it is without going OTT, an understated performance would be the smartest play IMO.
Like your article says give her an Eleventh Hour opener with the danger ramping up and up and not say a Christmas Invasion, keep her with a female companion at least initially before moving to a three team Tardis crew and most importantly don't make a huge deal about the change, obviously there would be differences but after the initial shock The Doctor shouldn't be constantly going on about it ( like he didn't with The Master)
Nice trailer by the way, only annoyance was the use of footage from The Flash, look me out of it at the end.
Fire at will
