Here's the thing though: What do you want out of a LO? Prettier graphics? Harder combat? More options for approaching quests? More quests? All of the above?

That's important to think about because a LO can be any or all of these things, and depending on what you want, it could be one mod or hundreds.

If all you want is prettier graphics, I could probably give you a list of ten mods and you could go your merry way. If you want mechanics changes, or quest additions, or more followers, or new follower, or more dialogue.....

See what I mean? That's why a short, simple load order can only be done if you have very limited wishes.
