No. Mods will not fix anything. Mods are there to add, not to repair or balance. Most Skyrim players cannot afford to rely on them, because we do not have access to them!
Just my 2 cents, was going nuts

EDIT: Please dont let this turn into a platform war. All 3 platforms are plenty viable, and no one is smarter or dumber for playing on one over the others. We all chose according to our means/preference and thats that.
The bottom line is that this game was sold on 3 platforms, and therefore should work on all 3 just as well. Proposing mods as a solution to balance issues, or bugs/broken quests is problematic, because it is something that fixes the problem for only 1 of those 3 platforms.
