Hey! Yes, I definitely think that's possible- I know people who have around 6 months left and are certainly not up to the stage you're at. You've done the hard work now, most of what you have left to do sounds like editing-type stuff, which can be time-consuming and boring but you'll be amazed at what you can get done in a few months if you work steadily. Just set yourself some deadlines and get final versions of the chapters to your supervisors asap so that by the time you've nearly finished, they have already seen it all. Good luck! KB
