Howdy, y'all.
I don't know a rosy red thing customizing 25th Anniv. figures other than swapping heads -- and in the case of the Trooper/Officer/Viper variants, helmets and combat harnesses/webgear.
Looking at a 25A Python Officer I bought (who now joins my "Viper Pilot", "Scarface", and Comic Officer/"recently-commisioned Air Trooper"), I thought back to my original ideas about the errors in the naming/colors of the original Python Trooper and Officer. Fortunately, Hasbro neglected to paint my favorite "Officer" detail -- the Pythonized kneepads.
Here's what I think they
should look like:

(To make
my version of the Officer, all I'd need is a Cobra Stinger/"Vehicle" Driver helmet, and someone to paint a Comic-based Officer/Air Trooper's harness in a matching pythonized green/yellow).
But this
is not what I'm asking for.
What I want to do is make a 25th Anniv. likeness of my Python Komodo pilot/intelligence officer. (I've woefully forgotten who created an actual version of my idea -- I think it was Carnage717 as the pilot for his Python Hurricane.)

Komodo is a
pythonized version of a
black Cobra agent I created a while back (before he gets his "normal" original uniform). Using 25th Anniv. parts, this is his newer body composition:
Copperhead v4's head and legs
Wild Weasel v6's torso
Crimson Guard v9-12's arms (or upper arms, if possible)
HISS Driver v2's lower arms (if possible and compatitible)
The end result would have an identical color scheme to the icon/character model shown above. Instead of the Cobra symbol shown above (on his right shoulder), the Crimson Guard emblem on his left shoulder should be detailed with red. If purchasing decals from cobrastickers.com, the diamond-shaped CG logos will also suffice. His accessories would be the M-16 and sidearm used by 25A Copperhead (and possibly Viper v16's backpack -- if it fits).
