I know it won't help if you're camping from one character to another, but if you're willing to start the game over, you could setup 2 eq2.ini files and 2 .bat files to start them.
Each .ini pointing to their respective ui directories:
best.eq2.ini
Code:
cl_ui_skinname profit
cl_ui_subdir UI/
brat.eq2.ini:
Code:
cl_ui_skinname brat
cl_ui_subdir UI/
Each .bat deletes the current eq2.ini, copies the one your about to start, and then starts the game. Create shortcuts to the two .bat files. It'll pop a dos box up, but that will go away once the game starts.
best.bat:
Code:
del eq2.ini
copy best.eq2.ini eq2.ini
eq2.exe
brat.bat:
Code:
del eq2.ini
copy brat.eq2.ini eq2.ini
eq2.exe
