You could do it with some tubing on the tapered stealth stem from PV. Other wise the tubing needed to connect the two (stem and elbow) are quite different in size. I'm sure you could rig something with different sized tubing, but why bother when the stem mates pretty nicely on it's own? I've been using the GonG stem a lot and I really like it. I just wish I'd gone with the carb version as lifting it out to clear a hit can be a tricky task when the stem gets hot next to the bowl.
Edit: I just realized Sticks was talking about the elbow screen and not the elbow. Feel free to laugh at me and disregard everything I just wrote.
2nd edit: @Sticks: The elbow screen is too large in diameter to be of use in either the bowl or the stem.
