Yes, but it would be less veritable than vanilla doors, for example: if you want to make a right facing door, you can just place it parallel to the wall, then flip it, but with a hobbit door you can't do that. Another thing is that the door would have to fit in with the adjacent blocks, so the door would have to be inset into the block,  which also means that it would have to open to the side of the block it is on, again, this makes it less vertile.
