I don't have any I can personally vet on the public internet. Most of what I've seen is on the GTCEu discord. Image searching "nomifactory" yields some stuff that looks about right. "Lawn base".
Back in the 1.4.7 days the biggest packs out there were kitchen sink packs like MindCrack with GT3 being the biggest single mod. The gregtech family tree has grown substantially and the largest branches are much more intricate than what used to be around. On par with Krastorio2.
