Hi InTheBasement.
I don't think dried pods would take the smoke very well. Most smoke fresh pods. But it's worth a shot. Maybe, make it a really moist smoke with water in a side pan, that might partially re-hydrate the dried pods enough to get some smoke into them. Sounds like a good experiment if noone else has done it.
from my (VERY limited) experience, it only takes a couple/few hours for the smoke to get into the chiles. When I did it, the pods were still very moist, so I proceeded to dry or freeze them. You could continue with them in the smoker until they are dried, but I have a feeling they would get REALLY smoky flavored if the smoke continued for the whole time they were in there drying.
Hopefully others who have done more smoking than I will chime in.
