This is fairly simple.

No_overheat patch will look for any parts with modules, producing malicious CoreHeat. You will need no radiators for converters, processors and harvesters affected, they will not need to warm up.

No_engineers will remove stock 5% cap on effeciency of converters and harvesters, they will run on their nominal effeciency, harvesters will run depending on resource abundance.
Example - Drill-o-matic JR is labeled as 0.3 ore per second, so on 8% deposit (0.08), [0.3x0.08] it will produce 0.024 ore per second.

Drill_collider makes drill collider 25 kerbal meters long, this is a dirty "fix" to fight bugged surface detection. But you still have to point it to the ground and to be landed.
