Flitwick-What Is he-and Which Side IS He On?

This is something that's occurred to me recently, involving Professor Flitwick. We don't know exactly what he is-I've seen speculation as to him being par house-elf, a dwarf/midget...BUT:
Inthe first movie, the scene where the one particular goblin at Gringott's takes Harry and Hagrid to Hary's vault, that goblin is Warwick Davis. (I recognized his voice.) THEN, when Harry get's to Hogwarts' and we see him in his various classes with different teachers, there's Warwick Davis again playing the part of Prof. Flitwick.
Now, this seemed to be a bit strange to me, so I thought maybe I was mistaken about the goblin; upon reading the cast credits at the end of the movie I saw that I was, in fact, correct-that he did play both Flitwick and the goblin. 
Now, it's fairly well known that JKR saw to it that certain things were included in the films. So, why have the same actor play two parts, especially since one part seems like nothing more than a "bit" part? 
If Flitwick is part-goblin, it could explain both his obviously powerful magical skills as well as his small stature. In almost every book, there arew references to the "goblin rebellions", of which there have been more than one.(There also hasn't been much mention of which side the goblins took during the previous war with LV, or Grindlewold, etc.
It was also pointed out that there may be some teacher recruiting for the Dark Side - that might mean recruiting for the side of a particular Dark Wizard, or just someone spotting likely candidates for the Dark Arts in general.
We know the goblins have had some (unknown) greivances with the WW in general; recruiting students to the Dark Arts might be seen as a way to disrupt the wizarding world in general. Dumbledore warns in OOtP that the wizarding world is going to have to stop treating other magical beings and Muggles as inferior, or pay the consequences.
So, if we have Severus Snape as the "obvious suspect" right from book 1 (Quirrel's words), Flitwick seems to me to be one of the top "un-obvious suspects"; and why have we never really heard the rebellions explained?
