Rift Herald's Presence

I think it would be really cool if during Rift Herald's presence in the baron pit, the pit was visually represented as his. Make it look like it belongs to the Rift Herald until he despawns for Baron's entrance. Add elements that would be directly tied to him, making it distinguish-ably his time, making him really own his time there. Just a thought, hope to see others' ideas for what those elements might be.
