Yes, I could see it not being an issue with Teflon tape and threaded sensors, but I think if it were me though, I would still want to see a hard copy of the white paper for that dielectric product stating that it is okay for the OP's application.
It would be interesting to see a thermal IR comparison of the coated vs. uncoated lugs when the services are under heavier load, like in the summer when things like chillers, etc. are operating.
I might just be me, but unless I can see it in writing, I would be concerned about how much area is actually conducting within those grease coated, round, smooth lugs they use in meter sockets.
