I am getting crazy… seems you had been right Firefly 16 …
I worked now long on that permap skinpack… Crazy stuff… Lots of headache…

I really tried to keep em short… they shaders had been first more descriptive … but it did throw that error… so I thought lets shorten them more… but nei 
There are 17 remapshader with 16 it works… So maybe we can remap the same shader 128 times, that i did not check. But remapping different shaders does not work.
Well this is pretty sad… as Allies had been almost finished… the last “ag” “I” is a new helmet…
So I have come to conclusion, only replace skins from team per map. Allies fit desert theme, Axis almost everything except snow. So I guess creating a skinpack where all classes share the same clothes would be make it possible… one helmet for all… and so on…
(5 helmets + 5 bodys + 5backpacks = 15… well no room to replace the hand, and have a naked body…
soo it needs allot of saving, beside that some maps also use remapshader.
Your idea Ragnar_40k did not work, making a logic which does kinda dispatch the remapshader commands did fail, I guess its because they are all recorded. So that a player which joins later has the same shaders as one which is allready in (G_FindConfigstringIndex).
So basically one can call maybe 128 remapshader , but not replace as many.
I still hope I am to tired and have failed -> overlooked something and it should work… lol
But I guess not.
Has anybody interest to help making that skinpack? Would need a light skinpack, which uses max 10 - 12 textures, so that they can be replaced by the mapscript.
