ESP-NOW frequency hopping spread spectrum

[shuptuu]

Hi,
Just wondering if it could make sense to implement a Frequency Hopping mechanism between 2 esp32 connected through ESP-NOW?
That is to say changing the wifi channel before each data packet transmission in a known/predifined sequence across the 14 available channels.
I made some test, changing the channel is quite quick, less than 1ms, so it's doable.
Or just scanning for the less crowded wifi channel before the ESP-NOW initialization is enough?
What do you think?
