Couldn't you have a younger version of the FIRST Doctor appear -- that could be a "nobody" and relatively cheap...and for some previous companions...how expensive would they be?
And for some of the older Doctors...did they HAVE to be their Doctor? Couldn't they be another Time Lord or other character that gives us a nod & a wink about their "true" identity?
Well, sure, you can do all of that. But still, every time you add a cast member, you have to cut back on something somewhere else. *shrug*
