Interesting, thanks for sharing

Hopefully the part connected with the tape doesn`t get too hot, you wouldn`t want to be inhaling tape glue vapors.
Other than that I think its actually a great idea. I do have the classic VG and it`s been basically ignored for years now since I got the GVG, due to it warming up too much and being harder to gauge the hit without seeing the vapor. So this modification you made is actually very relevant I think, maybe I try out something similar and if it works well, I can give the modified VG away to someone that could make use of it.
