FX stackable moderator Mod?

I don't know that it would help that much. What gun are you wanting to suppress? 
The best suppressors I know of are Weihrauch, Hogan, Donnie's, and maybe the Hugget. 
There is really no magic or breakthroughs in airgun suppressor design. Large volume, 2 or 3 chambers, and some dampening material around the interior of the outside wall. With high pressure gasses a small hole does not allow a lot of flow.
