Would this be for the purpose of cooling the vapor, or increasing thermal mass to apply more heat to the herb?
The later, to increase thermal mass and turn the omega into a kind of injection chamber like what some ball vapes use. Full disclosure though I do not own any ball vapes and am not super familiar with them but have done some research on how the cheap diy stuff works.
I'm not sure it would work with the herb being under the balls pulling through them. Pretty sure that the hot air from the balls has to be pulled through the herb, not pull the herb smoke through the balls.
Would have to get a way for the herb to be on top and still attach a whip or glass to it, and really nicely secure basket screens on both sides and use the megaadapter with screen Just in case.
Leaving the fan on at a high temp gets the steel HOT, adding balls and putting the herb on top could be worth a try. But really the kit as it is provides a really even extraction all the way through once heat soaked so it may not be worth the squeeze.
