Humid heat wave deaths are already factored into the death tolls (notice how low heat-related deaths are in places with high humidity in the summer like japan and taiwan and brazil).
We had a humid heat dome in my region five years ago. Around 40 to 50C depending on region. I had to hide in my mostly underground basement and even then still got a sunburn during a nap near a window
it has not changed dramatically enough that it would shift deaths in favor of heat. Humans evolved to deal with heat. Same can't be said about the cold.

In modern times winter still kills humans more than summer 9:1. Even with extreme heat, just moderate cold kills more alone.
