On a 2nd thought, ceramic could be an alternative: that would allow easy prototyping, provided the right alloy is available to begin with...
Now, lets go back to the ShotGun concept for a minute. I've fixed the Party-Beast In-Line Pump-Assisted Bladder-Conditioner v1.0 and turned it into what i tagged modestly as "HerbalAire ShotGun (Bag) Accessory"... It can be seen in these two videos:
HerbalAire ShotGun (Bag) Accessory
HerbalAire ShotGun (Bag) Accessory & Mist Maker Moisturizer
The Mist Maker Moisturizer is possible because of a convenient tube connector system based on this product:

Delrin 96760-PT series brass compression sleeve
Fellow Canadian citizens will find it at Rona L'Entrept as the Watts
A-8 and
A-107, respectively. The trick is to make a 3/16" hole to fit the A-8 sleeve tightly (insert from the internal side), on which hot glue is applied right before the A-107 sleeve is slipped on it (from the external side). The glue solidifies in seconds, turning the sleeves pair into a sturdy air-tight connector which is compatible with the HerbalAire 3/16" I.D. tubing. The rings are useles, they can be discarded.
This picture is an attempt to illustrate how my moisturizer was assembled:

3-Way Moisturizer (v1.2) with 18 x 22 inches Oven Bag
A closer view:
There are three items illustrated in this picture. Perhaps the most obvious one for HerbalAire owners is the grommets i've added to my connectors so they don't risk to slip out; that feature also makes tube handling easier because of the grip they provide. Next, i'd say it's not clear what that tiny in-line component between the bag and my moisturizer could be for... Well, this is a water droplet arrester or at least a prototype version of one. It can be seen in a
previous video that bubble splashes may throw water droplets right into the exit hole and then this water reaches the bag starting from there. One attempt to fix it was to use some in-line gas filter (yes, i did try to use less water and/or a bigger jar!):
Unfortunately, as anyone should expect of an item coming from a car department store, euh... It turned out i had to reject such a solution because of its smell (from the black rubber part inside)! The next picture shows a device i found in the aquarium section of another store:
I knew it would be safe but i had to buy a few and break them in order to remove the valve inside, then recombine its translucent recycled parts together to form an in-line cavity as that which i wanted... The later contraption works for short periods but water accumulates in it, eventually, which defeats its purpose because that water then can reach the bag after a while. As a result, i conclude a larger cavity would be required or i'll be restricted to using normal size HerbalAire bags when connected to this moisturizer prototype.
Last but not least, i simply don't use HerbalAire's bag clip system; a string and sticky ribbon work fine for me...
