more flexible items with blackout ward-detecting passive?

UNIQUE – BLACKOUT: When spotted by an enemy ward or Noxious Trap traps, gain Blackout over a 400-unit radius for 8 seconds (45 second cooldown). You Disabled Ward icon disable surrounding wards, as well as Exposed icon exposing stealthed wards and Noxious Trap traps. The effects linger for 2 seconds after you walk away. Basic attacks instantly kill revealed traps and do triple damage to wards.

How about putting the blackout passive on an item that can be built by more champions?

Why?

The umbral glaive feels very good on Pyke support, and might work as a utility option for roaming AD midlaners (talon, zed) ... because BLACKOUT clearing wards all the time is pretty useful. It's a tradeoff... more damage from duskblade, or a cheaper item and blackout vision control? Seems nice.

However, on non-AD champions it's really hard to fit into a build.....

I'd love to built it on Thresh or Bard in support, nidalee or gragas, leblanc, taliyah ... but it feels like a total waste other than the awesome blackout passive. Instead of a less-expensive less-damaging item, it would be an item that would tradeoff team utility -- instead of a sheild or movement speed boost, one would get blackout ward clearing.

Ideas

**(Idea 1) How about a more general tanky version of umbral glaive... sort of like rightious glory? **

Umbral Glory 2200g +30 armor +10% CDR +400 health +150% base health regen +100% base mana regen (discounted itemization to make it usable by non-mana users) UNIQUE BLACKOUT - reveals wards

Builds from Crystaline Bracer and Raptor Cloak

This item isn't practical for AD assasins like Pyke/Talon/Zed, but it's practical in tons of other situations.

Most supports. Situational Junglers. Vs a teemo to clear shrooms. Vs Shaco to see boxes.

(Idea 2) make a new "green" jungle item color.... which gets BLACKOUT, but smite has no active anymore?

**(Idea 3) Add the BLACKOUT passive to Morellonomicon ... **

make it sort of a "dual role" specialized item.. build it when you want grevious or ward clearing, or both.... increase it's cost to 3200g?

(Idea 4) AP item... spellpen and ward clearing

Umbral Wand 2800g +70 ability power +600 mana (or +300 health) +10% CDR +15 magic penetration PASSIVE-BLACKOUT: reveals nearby wards and traps

Would be built from Blasting Wand and either Lost Chapter (if mana) or Oblivion Orb (if health)....

(Idea 5) tank support item that earns BLACKOUT during one of it's upgrades?

Bullwork Relic - 400g +60 health +2 gold per 10 seconds PASSIVE: spoils of war

(on final upgrade) .. earns BLACKOUT.... only issue, this might become the "must buy" support item?

My idea here is to compromise early lane power stats for mid-to-late vision control advantage. If it's tuned right, pros would not buy it becuse they use so many sweepers and control wards... but low-tier supports would buy it, because it just makes finding and clearing wards "easier"...
