I read that on ESPNow you shouldn't have more than 20 boards connected.
So I was wondering, could you set up 2 ESPNow networks with each 20 boards and then connect one ESP boards from each network via I2C and so get a network of 40 ESPs?
Only just started playing around with these boards. Cheaper to ask than to buy and try.

No, because they use the same radio frequencies and using I2C you cannot place the two "router" ESPs far enough so the different network wouldn't interfere.
