Biggest mods in my pack are AAII, Angel's, Bob's, MadClown.

These show up in FNEI but have no crafting/uncrafting recipe:
Nitinol Plate (stack of 5)
Copper-Tungsten Plate (stack of 5)
Tungsten Carbide Plate (stack of 5)
Chrome Plate (stack of 5)
Manganese Plate (stack of 5)
Platinum Plate (stack of 5)

There isn't a stacked version of BCB (Basic Circuit Board). I'm using a workaround currently but it's not ideal.

Nitpicking:
Iron, Copper, Steel are inconsistent due to Angel changing the plate sprites:
Current plate sprite: https://i.imgur.com/Zaz5wAD.png
Mockup plate sprite: https://i.imgur.com/1p5uRw8.png

The sprite for the stacked version batteries is inconsistent due to Bob adding new types of batteries:

PS. The batteries could go either way; downgrade the 0.16.51 battery to the old one (duracell) or upgrade Bob's batteries to the new 0.16.51 battery.
