I have done this and you have the overall idea right. If your using iso I'm assuming what your really making is hash oil. Instead of painting your ciggys before you burn off the iso - do it after. The right time to collect the oil at the botton of the bowl is when it is still plyable and somewhat liquid (like scrapping wet resin outta a pipe). Now if you leave it exposed to air it will get hard. I cap mine into little vials and it stays liquid but thick. I painted straight oil onto the outside of the cig paper and let them dry. If your oil gets too thick at any piont you can add a drop of solvent (iso) to the mix and it will thin it out. As far as the smell, I have smoked the hash oil cigs around my kids....no smell comments but they are used to the smell of weed around. It was nice to take some smokes out to the garden with me and my nieghbors can't tell I'm smoking anything but a cigerette.
A side note - I have done the canna butter, tinacture, hash and hash oil. I love hash oil the most. It just is very easy to use for one person. If I want to inject my weed - drop or two of hash oil into a tiny pat of butter warmed in a spoon over a candle... yum stir it right into some coffee or hot cocoa or yogurt. Eating weed in under 5 minutes. Oh I feel like smoking it ... drop on my bowl or paint some on a cig. Easy to use, easily hidden and quite stoned
