Capacitative screens can have stylus made for them but it's typically not very logical. The stylus must be able to conduct electricity (thus the hot dog stylus used for the iphones in Japan and China lol). The reason the stylus was used for your mogul was because it was resistive, it was sensitive to pressure.
I will say this, that whole laser pointer idea you had got my inner nerd excited, but I think I would be concerned with a removable kickstand. I would end up losing it and there would just be a big red empty space in the back of my phone!
But, in conclusion, I would say don't get your hopes up for this unless you plan to do it yourself.
