Minerva & DD-Transfiguration Professors-have they been playing other Charactors?

Just a thought.

We know that Minerva and DD were/are Transfiguration Professors.
Do you think they may be playing other characters in the books?

I also have a question: Can a wizard transfigure into a cat (for 
example) and not necessarily be an anamagi?  

Can transfiguration be used (like when drinking polyjuice)to 
impersonate another character (without being a metamorph)?

Do you think any of the children (like Luna for example) are really 
Minerva, DD, or even Tonks for that matter?
