Made more heaters with plates of different thikness, to test temperature difference. Thermal camera shows only general picture, so used K-thermocouple via drop of rose metal to check most hot (~ center) and most cold (corner at wires side) points. Checks have been done at medium (~ soaking) and high (~ peak) temperatures.

4mm:

3mm:

2mm:

As conclusion - 4mm plate is good for any cases. It still can be cooled fast enough with fan.

What's next

PCB is already complete: https://easyeda.com/reflow/reflow-micro-table. But i'd like to draw device case and verify PCB outline and other things.
