Umbridge and Percy

My utmost apologies in advance if this has been thought of before...

I was listening to the OotP for the umpteenth time this morning and 
something struck me a little differently than before.....Percy's 
letter to Ron where he congratulates Ron for becoming prefect and 
then advises him to drop Harry as a friend and be loyal to the 
ministry....(Am.version, pg.296-298)I know it's been suspected that 
Percy might be a spy for the Order.  But can it be possible that he's 
actually under the Imperious curse, not by Fudge, but by Umbridge?  
After all, Percy seems a very swayable personality where his own 
advancement is concerned, not inclined to question authority, so 
wouldn't fight the curse, and we already know that Umbridge is 
capable of using Unforgiveable Curses. Percy refers to Umbridge as 
a "really delightful woman", which I find hard to stomach under any 
circumstances.And he seems to have had, and continues to have, quite 
a bit of contact with her.Could it have been her who convinced him to 
write that letter in the first place?
