Combining and  sounds like a great build path for tanky AP champions, but I also think there are a few problems with your item's stats and passives: by combining Sheen and Catalyst, you effectively only get 50 more health in terms of raw stats. At a minimum cost of 2400g, this would make Eternal Hammer of the Elders one of the least gold efficient legendary items in the game, as well as the legendary item with the weakest AP bonus.

The improved Valor's Reward passive looks fine, though 50 health regen per second in combat sounds quite strong. The main problem, though, is the abuse potential on the Spellblade passive. Any champion with a mana drain ability such as, or  could charge up their ultimate and then heal for a massive amount. Champions with high early mana costs like or  would get massive early game damage, whereas champions with decreasing mana costs like  or  would actually benefit less from the item as the game goes on. In any case, though, the damage dealt by this item would tend towards getting outscaled by Sheen's own on-hit proc in the late game, and also has the problem of working awkwardly in combos (if you're the kind of champion who initiates with a lot-mana cost skill, like or, the Spellblade proc will be really weak, and if you use low-mana cost spells in combat you won't get as much sustain). The other problem I see is that this gives two forms of sustain, both with a bit of abuse potential, which may be too strong on one item if compounded.
