Tank Junglers and AP Mids Cannot Coexist
Don't get me wrong, I'm ALL about some jungle diversity. I love playing tanks and you can't play very many of them top because they are immobile, poor duelists, and their mana costs are kept exorbitantly high in order to keep them in the jungle.
Since the mana regen nerf, AP Mids have been getting less popular, especially high mana cost Mids like Ziggs, Anivia and Swain. They are more dependent on blue than ever, at all stages of the game.
Tanks are expected to build mana as part of their build. That's why their costs are high and it's why their items give large chunks of mana. This keeps tanks somewhat relevant in the late game, but also ensures that even if they become unkillable they can't stay in a team fight for more than 10 seconds or risk going oom.
So there is no elegant solution here. The obvious solution of "both mid and jungle adapt with itemization or learn to manage their mana more carefully" doesn't work in practice, when Lee Sin, Zed, Katarina, and other mana less Mids/jungles remain strong players will simply choose these champions over a double blue-using team any time.
Does anyone have an idea for maybe some new items that may make it easier for tanks to give up blue?
as AP mid" or "tell the tank mana using jungler to build a 
".

love Rod of Ages. It gives them health, which makes them live longer, enough mana that they don't need blue, some sustain from the Catalyst, and AP that fuels their ability to deal damage. And pretty much anyone in the jungle that uses mana and doesn't like Rod of Ages probably likes either Frozen Heart or Iceborn Gauntlet.
