Random thoughts I'm coming up with from time to time, decided to write some down, may add to them later.  Hoping some of these mods exist and someone can suggest one.

Shor's Stone - Araca-not-a-phobia:  Have sex with all of the spiders (or quest pacify the usual ones there and spawn a giant one to worship) so you can tell Flinjar the spiders got what they wanted. He could have had Sylgja do it and solved the problem right away.

A vampire focused mod that either folds the Morthal "take over the town" quest into the Dawnguard Volkihar "go infect this NPC" quest chain, into a vampire intrigue quest chain, potentially making use of the Vampire Dens mod that adds some hidden "homes" and vampire NPCs to the major cities. (Could be either during or post Harkon's death). Miracle would be using Auriel's bow to darken the sun and complete the civil war with vampires, turning or killing the jarls, and eating the Thalmor for lunch.

A mini mod that spins off/requires the More Bandit Camps mod and moves the "disrupt the skooma operation" quest target to the Cammona Tong bandit camp. Cragslane is strictly a wolf fighting operation, with potentially some wolf loving (or wolf loved) girls in the cages. The Barkeep could actually keep the bar, and the gamblers could gamble if enough work was put into the mod.  I just want a new place to go drink and party.

Suspecting there is a way to change AI packages in game (you can make a follower a HF Steward, marriage, death of a shopkeeper results in someone else becoming shopkeeper, etc)... a mod that could copy the packages of one NPC and paste them to another. I'd like to move followers or other mod added "useless" NPCs to farms, lumber mills, inns and the like and clone the packages from the one of the NPCs to the "new hire". I think the My Home Is Your Home mods are supposed to do something like that, but the one I tried seemed to say "guard here" or "sandbox here" or "sleep here" and that was about it.  Other NPCs have wake up times, meal times, work times, break times, after-hours times, and then sleep times.  Maybe I just need a better mod.

Somehow change the dialog system so that random conversations using the right voice types can be used by any/all NPCs. I am really tired of Narri and Valga (and plenty other pairs) saying the same two things over and over and over. In Oblivion you'd get random different NPCs talking to each other, using lines that could mix and match. Wasn't that much variety, but at least it wasn't the same scripted thing endlessly.

I kinda wish more Inns had a basement level like Frostfruit does, or the Hall of the Vigilant. Visually the large posts could extend down to the second level. I forget where, but there is a room (or 3) with heavy beams across the ceiling as well that could be copied and a much larger basement room could really open up the place.
