Could be cool! Would be on a green base?
Green is cool! Might be neat to match the toxic green in that group buy if possible too?
I picture it as solid black for easy dyesubbing, nothing too detailed.
I'm thinking in terms of Buck Rogers, Venture Brothers, Forbidden Planet, etc.
Also I think a Mutant from This Island Earth from 1955 is a classic Sci-Fi Icon:Show Image(http://25.media.tumblr.com/tumblr_lmkzrg8Jpy1qbc1l7o1_500.jpg)
A MST3K cap, huh? :p
I think the only material suitable to dyesub is PBT so this is likely not possible.
What about getting techkeys to run it? The wario key is doubleshot then dyesubbed.
Sounds somewhat plausible, but I don't know how durable the pad print would be over time, and how well it would cover the Polycarb.
