Given the fact that I did not modify or touch the textures at all, I'd be very hesitant to add them here unless I got explicit consent from the original creator, or creators depending on whether you are talking about the creator of the models or the textures.
I hadn't really thought about the extra blasters since I figured most would use the High Quality Blaster mod instead. I am well versed in 3D modeling and image editing however, and would be capable of creating extra models or textures for this in the style of its original mod. If they are not too many, I may consider adding those here as a future release.
None. But you can edit the UTCs in the tslpatchdata folder yourself to add them. Note, however, that would only affect the stunt party members inside the party jail cell. If you choose Mission or Jolee as the jail breaker they would still end up naked, at least without some additional script work. Canderous as well, but he has his gear stored right next to his start point.
