If you have a mod with lots of different variants then you can make use of those for the different clothing UTIs. For example, DP_AtrisBA01, DP_AtrisBA02, etc. (if you follow my naming scheme). Of course you can edit the 2DA and change the texture naming scheme to whatever you want, and/or extend it to use the Atris robes model for the other body types which will also make use of texture variants.
