Personally I think playing as skritt would be a fun idea, besides tengu I would really like to see the skritt as playable learning more about the lore behind the skritt would be enjoyable for not just myself but for my little brother as well since he loves getting into the lore of the game, plus the thought of a skritt thief in and of itself just sounds fun.
I will agree with some of the others here that some of the ability ideas proposed are a bit on the op side but after some tweaking and consideration they seem very sound as it is and the ideas of how to bring them into this if you think about it like the asura thy have been driven out of there underground homes as well thanks to the fire dragon and (spoiler alert here) they do become part of the pact fighting against the elder dragons anyway that opens a bit of opertunity to bring in skritt characters since they are getting a bit more involved in the world.
All over I think this is a nice idea I say bring on the skritt characters (ps and tengu too lol)
