Hi,
You asked some time ago how long can you can leave dough or starter in a fridge. The question intrigued me so I left a couple of pizza dough balls in my fridge and went off to Singapore for several weeks and now back and the balls being around eight weeks old or so I pulled out the balls scrunched them up, threw them into a hot pizza oven and baked them, put some butter on them and tasted them. They were difficult to handle because as you know I like wet mixes but they tasted great. Touch more sour, soft chewy, great texture and full of character. So ... the answer to your question is that you can it seems leave dough in the fridge "indefinitely".
Hope it is of interest.
