Furnace getting affected by hot blocks

what if furnaces get a advantage/disadvantage that affects speed or fuel usage with nearby(1 block range) hot/cold(speed), heat preserving/heat running out blocks(fuel usage)?

hot blocks

- magma block

- lava

- heat block(education edition)

- other running furnaces

- fire

- torch

- powered redstone(little)

cold blocks

- ice variants

- prismarine variants

- soul fire

- water

heat preserving

- water

- clay?

- brick?

- stone?

heat running out

- air

- sand variants including soul sand

- metal blocks

- redstone variants that is not turned on

this will lead to interesting super smelter designs and make a little challenge to make it compact rather than building a wall of furnaces. also it will make furnaces 

any other block types suggestion is welcome
