Shen's definitely an option, I just think he's a little weird at the moment. I'm a little too confused by the AP buffs. The main issue I can see with it is that if he's 1v2ing he'd need to take teleport to ever use his ultimate during laning, and there'd be times when he couldn't use it even then, and that's a big problem imo :/. If you could get past that he'd be GREAT though, especially as that's another potential to synergize with Poppy's passive.

I don't have experiences with tank Gragas (AP Gragas wouldn't work that well just because of the aforementioned magic damage problem), but the main issue there is the lack of interrupt outside his ultimate. It's the same issue as Galio. Of course EVERY gank on that lane would result in 1-2 kills, but I just think it'd be too much trouble heading into late game where you face something like a Nunu ult and Poppy and Gragas have already blown their interrupts. Again, if you can get around that, it'd probably work like a charm.
