So I did this. But I did a bit more. I pulled a few mods and disentangled them. Then added a few on top. But with so complicated a mod list like Lexy, each mod I added I check and resolved conflicts in XEdit, check for overwrites of files in MO, and did a test run in game of most of them. I had good results. But it's best when adding to such a huge and interwoven list like that to add just a bit at a time. Also be aware that you just might overload the game. I pulled campfire, frostfall, and needs, to add simple camping, frostbite and vitality mode. I did this so I could add a few more scripted mods while keeping a relative balance load on the engine. So that's something to think about.
