Just felt like making some cards, decided to make one for each Naxx boss. Anub'Rekhan - 8Battle Cry - Silence each enemy minion, and create two 3/3 Crypt Lord tokens with taunt.6/6Grand Widow Faerlina - 6A player may destroy one of their mana crystals to give this -6/-0 until their next turn.8/4Maexxna - 8Battle Cry - Your opponent can't cast spells or attack on their next turn.6/6Noth, the Plaguebringer - 4~ can't attack. At the end of each turn, summon a random skeleton minion. (ranging from 1/1 to 4/4)3/3Heigan the Unclean - 6At the end of each opponent's turn, cause a 50% chance for each minion for that minion to take 4 damage.3/6Loatheb - 6Characters can't be healed or dispelled.5/4Instructor Razuvious - 4Battle Cry - Opponent gets 4 0/5 minions with taunt.5/5Gothik the Harvester - 3Adjacent allies can't be attacked. 2/4Patchwerk - 8Patchwerk attacks each opposing character instead of one.8/8Grobbulus - 5Taunt, Death Rattle - each character gains Death Rattle - Summon a 2/2 Ooze3/4Gluth - 6Charge, At your end step, summon 3 1/1 Zombie Chow.

Battle cry: Freeze all opposing minions8/8Kel'Thuzad - 10Battle Cry - Draw 5 cards.Death Rattle - Shuffle ~ into your deck5/5
You seemed to have thought these through, nice ideas in here but they would need lot of balance as it looks very op from where I stand
Let me change your mind
Four Horsemen would be hard to incorporate while achieving the flavor of the fight and maintaining balance, but here it goes...
Baron Rivendare - 10
Battlecry - Summon the horsemen.
Battlecry - Unholy Shadow - Reduce a target's health by 2.
Thane Korth'azz - 0
Battlecry - Meteor - Deals 4 damage split evenly (as possible) between all enemy targets
Lady Blameux - 0
Battlecry - Voidzone - Randomly deal 1 damage to an enemy and any adjacent allies.
Deal 2 damage to a random enemy every turn.
Sir Zeliek - 0
Battlecry - Holy Wrath - Deal 2 damage to a target, 50% chance to damage an adjacent target for 2 damage.
Its probably a bit OP, but I'd argue that its easier to deal with (initially) than Deathwing.
How do you dare to miss the more important card in Naxxramas?
Deathrattle: Put a copy of "Kel'Thuzad" in your hand.

I meant to put Mr Bigglesworth and 4horsemen, I copied the ideas from my phone and forgot to add them. Mr. Bigglesworth was similar to what you posted:Mr Bigglesworth - 2Death Rattle - Kel'Thuzad costs 2 less to play this turn.0/14 Horsemen was like this:The Four Horsemen - 10(Spell)Call forth the four horsemen! The four horsemen of Naxxramas share a health pool and can only be damaged once by each spell.Thane Kor'thazzTauntDeath Rattle - deal 9 damage divided evenly among all opponent's minions.3/11Baron RivendareCharge, ~ can only attack the target with the least health.5/11Lady Blameaux~ is immune while attacking.
