These are simply converted from the SE Mod, published with permission of Janquel.
Thanks to Janquel and team (see below for full list) for the patches!
If you like this version, please download and endorse the original mod as well.
I will be adding more ports (see below), but it'll be a little slow.

Original Mod Description (some info doesn't apply to this version):

It's me again, working at resolving potential conflicts with Cities of the North - Winterhold. PLEASE check the sticky on the posts tab, please bear with me, and  Each mod which has a patch is listed below, with specific details of all changes contained in spoilers, if necessary. All patches are ESP flagged as ESL, unless otherwise noted. I'm certainly more experienced than before, but I'm always learning, so if you run into trouble, please let me know and we'll see if we can work it out.

Please remember that patches sometimes involve Persistent references, so they will require a new save/playthrough. Before making a request for help, please
double check that the problem exists on such a new save.

Included Patch Descriptions (edited for LE)

Ported

3DNPCs/Interesting NPCs - shifts placed objects/markers to match new interiors. Checked with version 3.42. You will need a new game for this to work.


Amulets of Skyrim - Moves three amulets to their appropriate locations in the new interiors. Last checked against version 4.06

Atlas Map Markers - NOTE: Based off MCM version. Shifts map marker for Birna's Oddments to match new layout, adds map marker for Stonecold Fortress. MCM toggles supported. Checked against version 2.0.

Cheesemod for EVERYONE - Shifts a few added cheeses to match the new interior. Last checked against version 1.0.1

Cloaks of Skyrim - Moves two placed cloaks to appropriate locations in the new interiors. Last checked against version 1.2.1

Enhanced Lights and FX - One patch for simplicity's sake this time. Patch attempts to replicate the intention behind ELFX to the new interiors, however, due to engine limitations a few compromises were made. I'm looking for feedback on this one, for any interested. No changes made to the newly-added cell. If using ELFX Fixes, load after ELFX Fixes. Last checked against version 3.04.

ELFX Exteriors - Patch for outdoor lights which are added by ELFX Exteriors. Last checked against version 3.04.

Legacy of the Dragonborn - Moves a few fliers, drunk marker, Latoria, restores one bench used by a package, and a few items in Birna's Oddments. Checked against latest LE version.

Notice Board - Shifts the notice board to match the new inn exterior. Thanks to EiraSvero for the patch. BETA: It moves the board fine, but I can't get any of the boards to drop quests, even with no other mods (including the patch) active. I believe this is a bug on my end with the main mod, please let me know if you have any issues.


Might port

Artifacts of Skyrim - Revised Edition (unfamiliar, but very likely)

Harvestable Mammoth Skulls (unfamiliar, but very likely)

Immersive Wenches (unfamiliar, maybe)

Large Trees- for use with larger tree mods, to help with clipping on the Fortress bridge (unfamiliar, but very likely)

Installation
Use a mod manager/organizer to install, or drop the loose files into your Skyrim data folder. Patches should have their appropriate masters set, and should be loaded after any mods which they are patching. Some of the fixes in question are on persistent objects, and may require a new save.

Compatibility
I don't believe this should introduce any incompatibilities beyond anything which may be present between base mods. Let me know if you hit anything.
