Merging weapon/armor mods

[Skrypto2]

So, im trying to merge some mods into few esp. But ive got some questions about things im worried about.
If i merge, for example, lost longswords and lore weapons, will they be normally distributed to world, as they should in oroginal mods? And, for example, if i add to that esp thane weapons reborn, will i be still able to get that weapons from making quests, and they will not appear in loot or be given to bandits?

And another question, those weapons mod will work with weapon sheath redux?

Simply retextures of chest, locks and, for example, trees, merged into one esp, will work as texture pack?

Sorry for dumb questions, but im a little bit distrustful to that xD
