You will probably get some ripe peppers from the goat weed and the thai. Chinense are slower, and the superhot varieties are the slowest so you may get some pods, but no way they will turn red/orange before the frost. On the other hand, if the winter is normal or mild, and you have a way of sheltering the peppers and possibly supplying some heat on the coldest days you can get a huge head start on next year's growing season.
Last year we had a pretty mild winter in Houston and we put an improvised cardboard box shelter over the peppers on the coldest days. In mid February I cut the top 1/3 of the plants back and then just let nature take it's course. Year 2 has been going great, a huge first round harvest with first red pods on the goat weed in early may and continuous production through about a week ago. Now the plant is loaded up with a fresh batch of green pods that should come ripe starting early fall.
I'm assuming your climate is pretty similar to mine, so I say start those seeds now and take care of the young plants over the winter. You should have a huge harvest next year, including some ripe superhots in June-July next year, which will be earlier than most everybody else.
