Implementing this change would require fixing something that has been broken since Morrowind
Something else has been broken since Morrowind: Bethesda.
Only difference between Morrowind and Oblivion is the terrain.
Not true, there is whole list of differences.
Like?
Morrowind has no level scaling; enemy stats are fixed. Oblivion has level scaling.
Morrowind lets you summon many an army of minions at the same time. Oblivion only lets you have 1.
Morrowind has many different factions to join. Oblivion has the 3 guilds, and the Dark Brotherhood. That's it.
Morrowind has more spells. Oblivion removed Mark/Recall, Levitate, Jump, Sanctuary, Slowfall, Divine/Almsivi Intervention, Sound, Blind and several Summon spells.
Morrowind has 3 types of ranged weapons: bows, crossbows, and thrown weapons - darts, stars, and knives. Oblivion only has bows.
Morrowind has 22 weapons available in more than one material. Oblivion is 9.
Morrowind: spell casting can fail. The failure rate is influenced by your skill rating in the relevant school of magic, willpower, Luck, and your Fatigue. In Oblivion spells have a 100% success rate. Your Skill affects the Magicka cost.
Morrowind guards will try to kill you if your bounty is high. In Oblivion they will always allow you to pay.
Morrowind characters can have 9 pieces equipment. In Oblivion it is 6.
Morrowind spells have to be equipped like a weapon. In Oblivion you can cast them at any time with a separate key.
Morrowind magicka doesn't regen, you have to sleep or use potions etc. In Oblivion it regenerates over time.
Morrowind has 7 skills for different types of weapon: Short Blade, Long Blade, Axe, Blunt Weapon, Spear, Marksman, and Hand-to-hand. In Oblivilulz, there is just blade which governs all lengths of bladed weapons, and blunt which governs axes and blunt weapons. Spears do not exist.
Morrowind has 3 weights of armor, Oblivion has 2.
In Morrowind you can completely miss an attack, based on fatigue. In Oblivion you always hit, and the damage is based on their armor and skill.
Morrowind has 3 types of melee attack: chop, slash, and thrust. These are controlled by standing still, moving sideways, or moving backward/forwards respectively while pressing the attack key. Oblivion has only one type of attack initially, and then "power attacks" are learned as a player's skill with a type of weapon increases.
Morrowind blocking is based on the block skill level. In Oblivion it is done manually and you can block with hands, weapon, etc.
In Morrowind, running and jumping drain your Fatigue. Low fatigue lowers your chances of successfully accomplishing any task that requires a roll (hitting enemies in combat, casting spells, persuasion, etc). In Oblivlulz, tour fatigue no longer drains while you are running. Running only slows the rate at which fatigue regenerates. Fatigue also no longer influences the effectiveness of spellcasting.
Morrowind has three types of diseases, requiring three different cures. One of these, corprus, is unique to the main quest. Oblivion has 1.
Morrowind contains some cursed items. If you pick up one of these items, it causes a creature to spawn nearby and attack; most frequently this is a powerful Dremora Lord. Oblivion has no curses.
