My first thought is it's going to be very hard to get mech around three 90 degree turns in a way that's smooth, light weight, reliable, and inexpensive. Clearly it can be done through a series of cams and gears, but it's going to need to be precise to make it work smoothly. You could try a flexible push rod through a guide tube, but the action is not going to be smooth, and you're gonna have to really crank on it to make it work. My vote is give it up, unless you're totally in love with this blaster.

Your last idea about the trigger is definitely doable. In fact it's awesome. If you have access to a scroll saw, it's two minutes work. I'm thinking you could also accomplish that with a rasp in 20 minutes. Grab some 600 grit sandpaper and wet sand it to get a smooth finish, then use some furniture wax to give it a factory shine.

Heck, throw it in a box and send it to me, I'll take care of it for you ;-)
