Warm air intake (wai) with controller all mechanical

Thire is much talk of a WAI (worm air intake) and how it could be done , but alas the idea seems to get stalled when the power loss /loss of FE (Fuel Economy) form uncontrolled IAT. To cold / hot is bad for economy. Cummins stats 1%power loss per 10°f above 60°f. EG , A 250HP diesel will produce 240HP with the same fuel demand as 250HP at 90°f IAT (Intake Air Temperature) this is measured at the intake manafuld. So hears my Idea for controlling the IAT with a WAI
The old low tech.answer is found in the carburetor /TBI (Throttle Body Injection) air cleaner.

A bi metal adjustable thermostatic Vac.(vacuum) Switch

I need 2 454 snorkels or build my own custom to handal the air demand of pulling heavy grades at down to -40°c/f . This is intinded to mix the air hot with cold. To keep it in the happy zone 32° f-60° f.
Will update when I get parts to work with.
Suggestions welcome

Gumby stay flexible.
