In a nutshell. Say you have a bunch of new heads (as you apparently do). I want to add them to the available heads, not replace existing ones.
If you want to add new heads First thing you should do is to use kitty's PC mod as a refferance to combined others. What you will have to do though if you want the head to be selectable by any class you will have to add three rows for each head in appearance.2da useing KT you can do this quite easily just right click a row you want to copy then paste in a new row at the bottom of the 2da. So if you have a new female head depending on the race you will want to add :
P_FEM_A_SML_01 = scoundral
P_FEM_A_MED_01 = scout
P_FEM_A_LRG_01 = soldier
once you have that, you need to change the number in the normalhead column. So if you adding a new head you will also have to edit heads.2da. Add a new row after the last in heads.2da, now depending on wheather you have DS transitions for the new head you will have to add the file names into the appropriate columns if you only have one then just have the same texture name in all five columns(just be sure not to add the .tga extensions or your game will crash) now at this point if done correctly the new player heads will be usable in the char select screen although they will not have portraits, So you will have to open and edit portraits.2da copy one of the exsisting player rows and change the columns if this is the first new PC head then the the numbers in appearance.2da should be 509,510,511
appearancenumber = scout = 510
appearance_s = scoudral = 509
appearance_l = soldier = 511
then to add the portraits file name excluding the extension in columns baseresrefe to baseresrefvvve.
last thing you should do is select a box outside the last you edited and save the 2da's to override do the same for all three
here is a sample of the changes I made to the 2da's for the mod Im working

The way it seems to be working with the current crop of mods is if you have a new head, it replaces an existing one, or if you want to add a new color armour, it will replace the one already in-game.
If you have a skin that someone else made ,but it's is just the texture you can make it a unique armor. What you would need to do is copy the armors uti, change the number on the texture name to something unique. So if the texture name is PFBC07 change it to PFBC34 (or any number) and then in the uti you would need to change the texture Var to the number on the new texture.
