Well, I'll probably be looking at the same ones that I had hoped for in 2012: Lina Inverse, Toof, Liechtenstein, Mamoru Kusanagi, etc.
Some things that Chan & I have been talking about doing is a PewDiePie family group. If we do this, she'd be PewDie, I'd be Piggeh, and our baby would be Stephano. I haven't talked with her about this yet, but I'd also like us to consider Project A-ko as an option (me as A-ko, Chan as B-ko, and baby as C-ko).
There's probably some others that I've thought about before that would be possible contenders, or even some that I have yet to do, but I can't think of any such thing now.
