I've coded it. In a single file and just 1117 bytes cfg. I'll test it before posting it here.

Here's it:

Remove all files but ProceduralStart.version

Create ProceduralStart.cfg with following contents:

@PART[procedural*]:AFTER[ProceduralParts]
{
	@TechRequired = start
	@MODULE[ProceduralPart]
	{
		@TECHLIMIT,*
		{
			@name = start
		}
	}
	@MODULE[ProceduralShapeCylinder]
	{
		@techRequired = start
	}
	@MODULE[ProceduralShapeCone]
	{
		@techRequired = start
	}
	@MODULE[ProceduralShapePill]
	{
		@techRequired = start
	}
	@MODULE[ProceduralShapeBezierCone]
	{
		@techRequired = start
	}
}

!PROCFAIRINGS_MAXDIAMETER,* {}
!PROCFAIRINGS_MINDIAMETER,* {}
PROCFAIRINGS_MINDIAMETER
{
    start = 50
    sandbox = 50
}

PROCFAIRINGS_MAXDIAMETER
{
    start = 50
    sandbox = 50
}
!PART[pf_tech*] {}
PART
{
    name = pf_tech_fairing
    module = Part
    author = Starstrider42 (config), e-dog (model)

    MODEL
    {
        model = ProceduralFairings/Parts/base_standard
    }

    TechRequired = miniaturization
    entryCost = 0
    cost = 0
    category = none
    title = Procedural Start - all fairings avaliable right now
    manufacturer = Keramzit Engineering
    description = Unlocks all fairings and sizes
}
@PART[Kz*|SSTUBase*|SSTUHollowRing*]{
	@TechRequired = start
}
