The silicone sounds like a good idea- though it would need to be suitably chemically resistant if it was in contact with anything but glass.
I don't really see the point of the aluminium. Why would you want a heat shield?

Wrapping TC in aluminum foil is optional but if you don't do this silicone will stick to thermocouple and it will be impossible to take it off. As I
said before when you take off this sillicone shield KOH will react with foil but sillicone will be untouched.
Why it is important to have removable sillicone shield? Because sometimes you need to distill acids and sillicone will not withstand it.
Second idea that just came into my head is to wrap TC with Teflon tape - more chem. resistant than sillicone and easier to use.
