My initial thought was that you should get a smaller vessel, but thinking it through likely the CO2 would drive out any excess oxygen or the yeast would consume it. I think you should be OK. I would personally get a second smaller fermenter as it allows you to make a small and a large batch in parallel, which isn't a bad thing :-)
Try siphoning off a glass of the wine and adding a pinch of BiCarbonate of Soda or Calcium Carbonate, give it a good stir and see how it turns out.
