Some things that might help relieve your workload a tiny bit:
If Ruffled Feather replaces EDT2 in the install order, all conflicts seem to remain as they were, except The HD Enhanced Terrain page will need to be updated to hide /textures/terrain/noise.dds, or move HDET up the load order to before RF (which seems to be simpler.)
I don't see anything conflicting with QWM, is there any reason some mods are higher up the install order in STEP, other than conflicts which are shown in the MO information window?
EDT2 DB also doesn't seem to conflict with anything other than HRDLC, so could stay where it is, or move out of conflicting graphics to it's rightful place in Landscape.
From Terrain Bump:
- textures\landscape\fieldgrass01_n.dds <Still needs to be hidden/removed in RF, but the next 2 files are not in RF. It doesn't SEEM like any other files would need to be hidden/removed.
I have updated the mod wiki page as much as I can. I assume the esp is clean based on LOOT, it seems Lore friendly, and I'm pretty certain the textures are optimised. As always, feel free to smack me upside the head if I need it.
This is all based on the fact that I think RF replaces only the following:
Stalhrim of Skyrim
But doesn't replace:
I also installed Hairy Furry Pelts and I Hold Silver just for the hell of it. Will do a comparison some other time. It's 9am, I start work at 3pm and I haven't slept. Now is NOT the time to patch everything and fire up Skyrim
