Do you plan to make any more models or outfits using the Daz Curvy bodytype? Looking through the characters and outfits sections assets page, I realized that there are only a few models that use it (Elizabeth, Lulu, Elsa/Anna, and Liara), and a lot of the outfits are still DazV4.
Mad Moxxi, for certain! Beyond her and the others you mentioned, I don't have in mind any particular characters for the Curvy body.
In general I prefer canon body-shapes - Elizabeth and Elsa/Anna actually started as references to early Shadman work, and Liara was originally adopted from the modeler Urgarulga who made her Curvy for some reason before disappearing and leaving the model in a rough state. Lulu and Moxxi are canonically busty and wide-hipped, so putting them on the Curvy body was basically just exaggerating their existing features.
I'm certainly not opposed to it, but I just don't know who else to put on it!
