A Mrs. Figg Sighting?

No: HPFGUIDX 45322

After over 45,000 messages from almost 5000 members, I want to see 
if maybe -- just maybe -- we've all missed a Mrs. Figg sighting.  
Yes, yes, yes, we all know Mrs. Figg and Arabella Figg are the same 
person.  But what about this, from "The Dark Mark":

"Barty," whispered a witch in a long woolen dressing gown, "they're 
kids, Barty, they'd never have been able to --"

AND

"We're too late," said the witch in the woolen dressing gown, 
shaking her head.  "They'll have Disapparated."

OK, now.  Maybe it's me, but I find those two bits of canon to be 
really weird.  This witch knows Mr. Crouch well enough that she can 
address him twice as "Barty," yet he doesn't bat an eye?  Everyone 
else calls "Mr. Crouch" -- except Bagman and Dumbledore.  Whoever 
she is, she is apparently fairly high up in the Ministry.

Also, the witch seems to take up for Harry, explaining that he 
couldn't have conjured the Dark Mark.  She seems experienced, 
understanding how the Dark Mark works.  She knows that the 
perpetrator would have already disapparated, even while everyone 
else is lighting their wands and still searching.

Every other person in that scene is identified:  the trio, Mr. 
Crouch, Mr. Weasley, Mr. Diggory, Winky, Mr. Bagman.  But for some 
reason, the witch isn't given a name.

Could it be . . . Mrs. Figg, fulfilling her role as guardian to 
Harry?

Cindy -- hoping the answer is embarrassingly obvious
