I just booted a single player world up now with it, and it's AWESOME. I actually didn't realise how many Pokemon there were! They even cry their own name. I was actually surprised at some of their sizes; Kadabra was bigger that I imagined haha.
That sounds like so much fun! Thanks for thinking of me; shoot me the IP some time and I'd love to join you! Considering the sheer amount of Pokemon available, and the numerous possibilities Minecraft already presents I can only see a super mega ultra awesome event coming up, haha. :D
Give it a try some time? :D Me and Olli and in the process of organising a Pixelmon event for PC (will be in a month or so since we're still making the map haha) and we'll need about 8-12 players, so I figured you'd be near the top of our list on people to invite before public entry starts! Try it some time and let me know if you'd be up for a whole event based on it? :)
