You could probably cast something in plastic, though looking at the pic you might be better off just learning to adjust to the length. In any case, heres what you'd need
So take the clay and make yourself a new fingertip, with a pocket for your finger stub to go in (mold it around your finger). Take it off and coat the outside with the latex, thin coats letting each dry until its like maybe 1/8 to 1/4" thick. keep the pocket clear so you have somewhere to pour the resin. once it dries peel it off the clay and you'll have a mold.
mix the resin and pour it in, swirling it around, in small amounts. the point here is to build up thin layers until its sturdy. it should cure pretty quickly in small quantities. once you've got enough, peel the latex off and you have a new fingertip. if the latex is too floppy to hold its shape you can use like plaster of paris or something to make a cast around it for stability
the end result is going to be hard plastic like a hockey mask. you can sand it smooth and make adjustments once its done. google "slush casting" for better instructions on it.
its probably going to take some trial and error to get right, but for something that small you'll have plenty of extra supplies. you'll probably want to put something on the fingertip like a piece of felt so it has some grip, and figure out a way to attach it too.
good luck dude.
