You're right, this is a simple 2da editing.
You will have to modify the Appearance.2da file. The labels you are looking for looks like "P_FEM_A_SML_01". There are many of them, one for each head and each class. The one from the quote is Asian. SML means it's the Scoundrel look. MED are scouts and LRG are Soldiers.
Look for a column called "modelb". This is the actual model for basic cloths.
In your file it should be "N_RepSol".
Change it to
"PFBBS" for female Scoundrel, "PMBBS" for male Scoundrel
"PFBBM" for female Scout, "PMBBM" for male Scout
"PFBBL" for female Soldier, "PMBBL" for male Soldier
Do exactly the same in the next column called "texb".
I'll look into the Bandon problem is I can download the mod you're talking about.
