That's what the flow control is for. Most older Jap vehicles have them, they're cable actuated. If you're good enough with electronics, you could wire up an ARDuino or something similar to control a stepper motor with a thermostat circuit to constantly adjust the valve to keep a specific IAT setting. That would prevent the over-hot intake in the summer.

Although, if your hottest setting only gets you optimal temps, it's not going to get any worse in the summer. Your thermostat controls the engine coolant temp regardless of season.

Also, if you started to overheat to the extent that the intake heated up too much, it would act as a self-cooling device. The hotter the intake air is, the less fuel the engine injects, so the less heat is released into the engine. It's sort of self-regulating. Thats why I like the idea so much.
