I would imagine it would work fine with 'the machine' it's basically an analogue conduction/convection hybrid vaporizer. Not the most efficient but I've read it can be effective, I would be more worried about the metal the chamber is built from than I would about the wool. **EDIT I reread your post and saw it's glass, so basically steel wool wedded up inside a "meth whistle" type pipe? That should work fine, have a friend with you - YOU DON'T WANT TO BURN YOURSELF ** I have a VV mesh RDA coming myself, I did consider building a machine myself but I found the thread on 3 to 1 CBC carts and have CBC so I figured I'd try that first, my VV should be here soon. Plus, I really don't like the idea of using external heat sources considering what happens when it's done correctly.
