Some figs have two crops a year here. Maturity for my 'Celeste' is 4 months for the fruit. I harvested the first crop a few weeks ago, and it is putting on another start now.
So, I'd bet if you can get your overwintered trees setting fruit by May, (in a warm winter) you might have ripe fruit by the end of August. Bring them into the sun indoors, earlier than it is safe outdoors you might have even a better shot at some fruit. Get it leafing out in a sunny window in March?? Big pot with casters on it, right?
