Setting aside classes for a second. If it were likely that the other players were going to be playing pretty upright characters, I might go the Avengers route and design something a little more Loki and a little less Captain America. Not evil, but something a little more sly.
In general the party tends more selfishly out for their own interests than beholden to uprightness. I'm not sure playing an angel race will change that - but should be interesting to have that be more of a dynamic.
