Ultra small ESP8266 node with 2 channel relay&temperature&dimmer Project

Hello There !
for a past few months im working on ultra small (to fit behind switch ) ESP12F node to controll lights ( along with dimming function ) and temperature measurment.
I have done some tests - and so far so good but i need some help designing a proper PCB.
Here is what i`ve got :
Relays are DIP8 AQH3223 which can handle up to 250w ( perfect for lighting isn`t it ? )
ZeroCross detector PC814 with two high power 68K resistors
and 1-Wire temperature sensor.
And 3d design( without dimmer parts )
Screw terminal - AC OUT
JST 3PIN - temperature sensor
JST 3PIN - Switch actuator
JST 2PIN - power.
so the goal here is to make it as small as possible ( sandwitch style :D) ( imagin there are 2.0mm pitch goldpins as connectors between boards - could not find them in KiCad.. )
Both, dimmer and relays has been testes and working with attached schematic so i would like to know if there is anyone who could help me designing a proper PCB for this thing ?
