BTW I have had some successful crosses quite late in the season, so if you have any flowers coming at all I wouldn't pack it in. Personally I feel that those stressed crosses which came in cold and darkening days had some special characteristics and unexpected traits/strengths. So there's nothing wrong with pursuing a cross of opportunity, even if it isn't what you had planned.
That is, depending on your goals and strategy for getting there.
As long as you can get the fruit to 'green ripe' stage or close, you can bag it and let it ripen indoors and get viable seeds.
