Thanks all for the feedback. Some great ideas. I think I will be making it a dynamic dungeon if I can. I think it sounds like a great approach.
Already part of the plan. With the orc horde outside, the evil guys behind the scene will try to frame the Lord Warden by using shapeshifters to impersonate him and commit murders. Whether the PC's manage to solve this will make a huge impact on the siege.
How about using the siege as a backdrop for different story? Say the PCs have to find a lost artifact or rescue a princess in the middle of the siege. This works best if the castle under siege is falling and the PCs will have to deal with invading forces while trying to accomplish their goals. Even more dramatic if they have enemies on both sides of the battle, perhaps an evil prince is trying to get away with the princess or the corrupt high priest trying to steal the artifact that the PCs are looking for?
