Indeed the timing is not good. Nevertheless, it clearly depends on what you have in mind. If you choose to play something violent, then it becomes risky because it could be misunderstood by other players. Remember, people on disco don't really know each others and there are a lot of very different people here. This means you will have to explain carefully the background of the faction. Additionally, as a preventive action, you should probably justify why you want to play such faction and clarify that you do not endorse such behaviour in real life.
In summary, it might be risky and if you do, you will probably have to provide a lot of rp and oorp explanation. Actually, it would be easy to do with friends around a table but I am not sure it's feasible on disco.
