Hi Marty,
This may be going the opposite direction than you want to go, sounds like you want more heat. I don't like pepper beers that are too spicy to drink much of so I have a technique I've used a number of times that gives a great complex pepper flavor and aroma but isn't too hot. I cut a blend of peppers in half and remove the seeds, then roast them on an open flame, then peeled off the skins and then put the peppers in a hop sack right in the keg. You could put it in your secondary if you wished for a few weeks. I used a couple of jalapeños, an Anaheim, poblano, Serrano and maybe some other peppers- basically a mix of whatever I could get my hands on.
