Nice idea, but does Draco even know who Tonks is, let alone know what
she looks like?

I don't think he has hung out with her - she may be his cousin, but
that side of the family was zapped off the Black Family Tree. Who in
their family kept in touch with Andromeda and the Tonk's family?

lizzyben:

Well, he may not know much about her, but he probably knows that
they're cousins. But for Polyjuice Potion, it doesn't really matter
much how much he knows about Tonks - he just needs to know her name,
know that she's an Auror guarding Hogwarts, & swipe a few hairs. Draco
isn't planning on being seen by people in his "disguise" - he just
needs a short, temporary disguise for entering the ROR. He also wanted
to be able to lurk near DD's office so that he would know when DD had
left Hogwarts; this is why Harry saw "Tonks" near DD's office. Draco
was trying to figure out when DD leaves Hogwarts so that he could time
the Death Eater entrance to occur during one of DD's excursions.

Looking at it from Draco's POV, he's mostly thinking about keeping
Harry, Snape & DD from figuring out his plan. He doesn't know (or
care) about Trelawney's sherry hiding. Isn't it interesting that
Trelawney was able to enter the ROR while Draco was there, yet Harry
could not? Seems like females could enter the room. And Tonks would be
a good person to impersonate because her presence in Hogwarts isn't
suspicious. Yet she's also an outsider w/o an expected routine or
schedule, so there's less likelihood of someone seeing both "tonks" at
the same time. When Harry mentions seeing "Tonks" outside the ROR, it
raises some eyebrows, but no one immediately suspects that it was an
impersonator. 

I just don't see why Draco would make Crabbe & Goyle become little
girls - the ultimate humiliation for a teenager!  They could've
impersonated first-year boys instead w/o much difference. But it makes
sense if only girls could enter the room. This is Draco's own
idea, different from the stairs or whatever else. He sets the
parameters of the room of requirement when he tells it what he
"requires" - Draco would just need to say that "I need a room that
only females can enter in order to repair the Vanishing Cabinet". And
the main point of that limitation was simply to keep Harry, Snape, &
Dumbledore from learning what he was doing. Pretty clever, really. 

Anyway, I'm not really invested in this theory, but it seems like
Polyjuice Potion was used by more people than just Crabbe & Goyle.
There was a whole vat of Polyjuice Potion in the dungeon - IMO a lot
of people weren't who they seemed in HBP.
