Not sure if I follow the aim here. Is it a challenge or a workshop to help people scratchbuild?
I never build OOB so all my models have a degree of scratchbuilding, sometimes just a few minor details, sometimes a complete rework as was the case with my Tamiya Saladin which only used three of the original parts.
		
		
	
	
		 
	
		 
	
I am going to be a grumpy old man and suggest that the hardest thing about scratchbuilding is not the use of tools/materials, it is the visualisation of the item that you want to build. All bits of machinery basically break down into geometric shapes;- circles, squares, spheres, cubes, etc. It makes no difference if you want to build a gearbox for a F1 car, a cupola for a tank or an engine nacelle for an aircraft, the starting point is to look past what everone else sees and recognise the componet shapes.
My current, stalled, build is a Tamiya Chally 1 which has recieved some scratchbuilt parts;-
