If anything, it's going to be worse, not better.

It's still a little early for me to re-weigh in on this thread, but having "thrown" a little pollen around -- Hey, 95 is beautiful banana weather -- it does seem to speed maturity a little bit, though I'd be quite skeptical about "adding pollen" to reduce flower time/add potency unless more information surfaces on the subject or you're willing to make mistakes.

This thread has taken an interesting evolution. I like it. I too have been playing with tempatures. I live in Nevada so it gets really hot in the summer. I have one of my flower tents presently set up where it is at about 68f during it's day time (the air coming out of the 1000 hps is only 75f as I have a really great system set up right now where I can individually control different tents all at the same time.) and 55f during the dark hours from day 40 on of 12/12.
In my last harvest, I finished a New York City Diesel that is a dark purple throughout the budz. To my knowledge that is not even a purple strain but purple it is. I will have to try what seabc was talking about wit the pollenating in late flower thus swelling the calyx. I like that idea.
