Well technically you are making a HUD already for the 1 texture applier right? Well instead of just using one or two buttons on that HUD for perhaps different layers also, just put all of the buttons in one big HUD with all the different colors and layers. It would really depend on what appliers you are working with and how their scripting works, but for most appliers it's not difficult to make larger HUDS with more buttons.
